A 5,000 kg truck moving at 8 m/s has the same momentum as a 2,500 kg car. What is the velocity of the car?
Answer:
16 m/s.
Explanation:
The following data were obtained from the question:
Mass of truck = 5000 Kg
Velocity of truck = 8 m/s
Mass of car = 2500 kg
Velocity of car =..?
Next, we shall determine the momentum of the truck. This can be obtained as follow:
Mass of truck = 5000 Kg
Velocity of truck = 8 m/s
Momentum of truck =.?
Momentum = mass × velocity
Momentum = 5000 × 8
Momentum of the truck = 40000 Kg.m/s
Finally, we shall determine the velocity of the car as follow:
From the question given above, we were told that the car and truck has the same momentum.
This implies that:
Momentum of the truck = momentum of car = 40000 Kg.m/s
Thus, the velocity of the car can be obtained as shown below:
Mass of car = 2500 kg
Momentum of the car = 40000 Kg.m/s
Velocity of car =..?
Momentum = mass × velocity
40000 = 2500 × velocity
Divide both side by 2500
Velocity = 40000/2500
Velocity = 16 m/s
Therefore, the velocity of the car is 16 m/s.

how the kinetic is transformed into potential energy in the Newton's Cradle example
Answer:
for example,lets say we lift the ball on one end up a certain height and then release it when the ball falls and strikes the next ball beside it,it transfer its kenitic energy to it.
Answer:
See the explanation below
Explanation:
The principle of Energy Conservation tells us that energy is transformed from kinetics to potential and vice versa. That is, the potential energy is transformed from potential to Kinetics as the height of the body decreases with respect to a reference level (level where the potential energy is zero), but as the potential energy decreases the kinetic energy increases, this increase is represented by the increase in speed. At the moment that the potential energy is zero, the kinetic energy is maximum i.e. the body experiences maximum velocity. And when the kinetic energy is minimal or zero, it tells us that all the kinetic energy has been transformed into potential.
1. What is the current in a 160V circuit if the resistance is 20?
2. What is the current in a 160V circuit if the resistance is 10?
Answer:
8 amps 16 ampsExplanation:
ohm's law is V=I•Rto get current you need to rewrite the equation to I=V/Rso for problem one it is 160V/20ohms which equals 8ampsfor problem two it is 160V/10ohms which equals 16ampsa good way to remember ohms law is this

Some researchers are developing a new fertilizer designed to improve the growth of plants in hot, dry climates. The fertilizer was applied to one hundred desert plants in a greenhouse. The average daytime temperature in the greenhouse was 90°F, and the humidity levels were low. Which is best for the researchers to do next?
Answer:
See the answer below
Explanation:
A compare plants that received fertilizer to similar plants that received none
B begin selling the fertilizer to gardeners living in hot, dry climates
C change the conditions in the greenhouse and retest the fertilizer
D test the fertilizer on plants that are adapted to cooler climates
The best thing to do next for the researcher would be to compare plants that received fertilizer to similar plants that did not receive the fertilizer in order to be able to arrive at an inference of whether the fertilizer is effective or not.
Without comparison, the researchers cannot attribute whatever they observe in the plants to just the effects of the fertilizer. There should be a control group of plants that would be subjected to the same conditions except for the addition of the fertilizer. Whatever differences that are observed in the growth of the two plant groups can then be effectively attributed to the fertilizer.
The correct option is A.

500.................The BMW has an 85L tank while the Cadillac has a 25 gallon tank. Which one has the larger tank?
85 Liters would be around 19 to 20 gallons so it's most likely the Cadillac
If The BMW has an 85 L tank while the Cadillac has a 25-gallon tank then the Cadillac would have a larger tank because its 25-gallon tank would be equivalent to 94.635 liters.
What is density?It can be defined as the mass of any object or body per unit volume of the particular object or body. Generally, it is expressed as in gram per cm³ or kilogram per meter³.
As given in the problem, the BMW has an 85L tank while the Cadillac has a 25-gallon tank,
1 gallon = 3.7854 liter
25 gallons = 25× 3.7854
= 94.635 liters
If the Cadillac had a 25-gallon tank compared to the BMW's 85-liter tank, the Cadillac would have a larger tank since 25-gallon tanks are equivalent to 94.635 liters.

8. What are elastic and inelastic collisions?
An elastic collision is a collision in which there is no net loss in kinetic energy in the system as a result of the collision. Both momentum and kinetic energy are conserved quantities in elastic collisions.
An inelastic collision is a collision in which there is a loss of kinetic energy. While momentum of the system is conserved in an inelastic collision, kinetic energy is not. This is because some kinetic energy had been transferred to something else.
Please answer this question and give a justification.

A cannon shoots a cannonball from ground level at an angle of 60 degrees from the ground with a total velocity of 25 m/s. solve for the time it takes for the ball to hit the ground.
find the weight of the following mass;
(a) 220g
please show the formula
Explanation:
weight=mass*gravity
w=mg
first change 220g to kg like this
1kg=1000g
?=220g
1kg*220g/1000kg=220/1000g
mass =0.22kg
now we can continue
w=0.22kg*10m/s^2 or w=0.22kg*10N/kg
=2.2N =2.2N

An airport has runways only 145 m long. A small plane must reach a ground speed of 44 m/s before it can become airborne. What average acceleration must the plane’s engines provide if it is to take off safely from its airport?
Answer:
The value is [tex]a = 6.676 \ m/s^2[/tex]
Explanation:
From the question we are told that
The length of the runways is [tex]l =145 \ m[/tex]
The required ground of a small plane is [tex]v = 44 \ m/s[/tex]
Generally from kinematics equation
[tex]v^2 = u^2 + 2as[/tex]
Here u is the initial speed of the plane which is 0 m/s
so
[tex]44^2 = 0^2 + 2 * a* 145[/tex]
=> [tex]a = 6.676 \ m/s^2[/tex]

In 1940, the Tacoma Narrows Bridge across the Puget Sound collapsed. The bridge was a suspension bridge. The wind blowing through the narrows matched the natural frequency of the bridge. This resulted in a large movement of roadway, which eventually caused the bridge to fail. What characteristic of waves caused the bridge to collapse? Absorption, because the bridge absorbed all the energy of the wind diffraction, because the wind moved around the bridge, which set the bridge into motion interference, because constructive interference occurred when the wind frequency matched the natural frequency of the bridge interference, because destructive interference occurred when the wind frequency matched the natural frequency of the bridge
Answer:
interference, because constructive interference occurred when the wind frequency matched the natural frequency of the bridge
Explanation:
Wave interference occurs when two waves with identical wavelength, velocity, frequency, and amplitude meet each other when the waves travel along with the same medium.
The characteristic of waves that caused the bridge to collapse is interference because constructive interference occurred when the wind frequency matched the natural frequency of the bridge

a jogger runs a distance of 100m and accomplished his feat in 30secs . What was his speed?
Answer:
His speed was 3.3
Explanation:
To find his speed all you have to do is to divide his distance ÷ time. Since your solving for speed all you do is divide distance ÷ time to find out your speed.
the mass of a car is 1000 kg. how much force would be required to accelerate the car at a rate of 3 m/s^2
Answer:
The answer is 3000 NExplanation:
The force acting on an object given the mass and acceleration we use the formula
force = mass × accelerationFrom the question
mass = 1000 kg
acceleration = 3 m/s²
So we have
force = 1000 × 3
We have the final answer as
3000 NHope this helps you

A car is travel with velocity of 150 km/hr east. It traveled a distance of 500 km. How long did it travel for.
Explanation:
V= s / t
150 km/hr = 500 km / t
t = 500 km ÷ 150 km/hr
t = 10/3 hr (3 hrs 19 mins 49 sec)?
I'm not sure tho^^
Answer:
[tex]\boxed {\tt \frac{10}{3} \ hours}[/tex]
Explanation:
Time can be found by dividing the distance by the velocity. Use the following formula:
[tex]t=\frac{d}{v}[/tex]
The distance traveled was 500 kilometers. The velocity is 150 kilometers per hour.
[tex]d= 500 \ km \\v= 150 \ km/hr[/tex]
[tex]t=\frac{500 \ km} {150 \ km/hr}[/tex]
Divide. Note that the kilometers, or km, will cancel each other out.
[tex]t=\frac{500 \ }{150 \ hr}[/tex]
[tex]t=\frac{10}{3} \ hr[/tex]
[tex]t=3.3333333 \ hr[/tex]
The car traveled for 10/3 or 3.3333 hours
