How much time will it take an armadillo traveling 0.1 m/s to go 2010 meters?

Answers

Answer:

20100s

Explanation:

After this first encounter, the bird then turns around and flies from the runner back to the finish line, turns around again and flies back to the runner. The bird repeats the back and forth trips until the runner reaches the finish line. How far does the bird travel from the beginning (including the distance traveled to the first encounter)? Answer in units of km

Answers

Answer:

The appropriate answer will be "8.378 km".

Explanation:

The subsequent trip device runner hits B by repeating the bird. Then the time taken by that of the runner around P to hit B would be:

⇒  [tex]P=\frac{1.2556}{7.3}[/tex]

        [tex]=0.172 \ hr[/tex]

Although in this time bird has always been perpetually flying.  

Distance covered by bird even before runner approach from P to B will indeed be:

=  [tex]29.2\times 0.172[/tex]

=  [tex]5.0224[/tex]

Apart from the first encounter, the overall distance traveled by bird would be:

=  [tex]5.0224+3.3556[/tex]

=  [tex]8.378 \ km[/tex]

Alberto is on his daily commute. While texting, his car veers of the road and hits a tree, coming to a complete

concepts of momentum, kinetic energy, and force to explain why Alberto was able to walk away from the

Accident.



Answers

Answer:

Please find the answer in the explanation below.

Explanation:

Given that Alberto is on his daily commute. While texting, his car veers of the road and hits a tree, coming to a complete halt. As state law required, he was wearing a seatbelt, and walked away from the accident uninjured.

To use the  concepts of momentum, kinetic energy, and force to explain why Alberto was able to walk away from the  accident,

According to the Newton's second law of motion, the rate of the change in momentum is proportional to the force applied. that is,

F = ma

where

F = the force that caused the car to accelerate

m = mass of the car

a = the acceleration of the car.

As the car accelerated, the kinetic energy produced caused the car to hit the tree.

But according to the Newton's third law of motion, which state that;

in every action, there will be equal and opposite reaction.

The seat belt provided the reaction opposite to the action produced by the force. Which eventually halt the Kinetic energy of the person and prevented him from being getting injured.

Alberto was able to walk away from the accident because he had his seat belt on according to Newton's first law.

According to Newtons's first law of motion, an object will continue in its state of rest or uniform motion unless it is acted upon by an external, unbalanced force. This law is the reason why a passenger quickly moves forward when a car stops suddenly.

Alberto was able to walk away from the accident because he had his seat belt on which prevented him from being thrown out of the windscreen. The momentum and kinetic energy of the car is not conserved because the car sticks with the tree.

1. List the point where the car has the greatest potential energy.
2. List the point where the car has the least potential energy.
3. List the point where the car has the greatest kinetic energy.
4. List the point where the car has the least kinetic energy.

Answers

Answer:

1) The point where the car has the greatest potential energy is Point A

2) The point where the car has the least potential energy is Point C

3) The point where the car has the greatest kinetic energy is Point C

4) The point where the car has the greatest kinetic energy is Point A

Explanation:

The potential energy of the car is given by the formula, PE = Mass × Gravity × Height

Therefore, as the height increases, the potential energy of the car increases

The total mechanical energy of the car, which is constant, is given by the following equation

The total mechanical energy = The Potential Energy + The Kinetic Energy

Therefore, at the point where the potential energy is lowest, the kinetic energy is highest.

Answers

I can’t see a picture but it’s most likely point one is at the top of the roller coaster. If it is, it has more potential energy because it is at the top, it has more potential to gain more energy.

Answer:

Answer:         1/17/2020

Potential energy is directly related to the height of an object. Point 1 is higher than point 4, so the potential energy is greater at point 1.

A rock is thrown downwards from the edge of the Grand Canyon. With
what velocity will it hit the donkey-riding tourist who is 40 m below?

Answers

Answer:

Vf = 28 m/s

Explanation:

In order to find the final velocity of the rock, we will use the 3rd equation of motion. The third equation of motion for vertical direction is written as follows:

2gh = Vf² - Vi²

where,

g = acceleration due to gravity = 9.8 m/s²

h = height dropped = 40 m

Vf = final velocity of the rock = ?

Vi = Initial Velocity of the rock = 0 m/s (since, rock was initially at rest)

Therefore,

(2)(9.8 m/s²)(40 m) = Vf² - (0 m/s)²

Vf = √(784 m²/s²)

Vf = 28 m/s

As you add heat, what happens to the kinetic energy of atoms?




Answers

The atoms in a hot object move faster than atoms in a cold object.

Answer:

The atoms in a hot object move faster than atoms in a cold object. The atoms in a hot object have more kinetic energy than the atoms in a cold object. Adding heat to a substance will make the atoms vibrate more and when heat leaves the substance; the atoms will vibrate less. Potential energy is stored energy.
