Please help me please I need someone to help me with all this question 1) How do we calculate the momentum of a race car? What part of this changes during a collision? 2) What happening to the momentum of the car when they crash? 3) how does impulse factor into this? 4) what type of collision is it ( ideally) when cars crash into this SAFER barrier?

Answers

Answer:

Explanation:

1 ) Momentum of a race car = mass of car x velocity of car . During a collision , an external  force acts on the car which changes the momentum of the car in the direction in which force acts .

2 )

The momentum of the car decreases as external force acts against the momentum . Sometimes when external force is very high , direction of momentum  is reversed .  

3 ) Impulse is force x time of action of force . Generally time of action of force in large collision  is very small . so it is calculated very carefully .

Impulse = change in momentum .

4 ) The type of collision is inelastic . In this type of collision , car crashes into safer barrier , sticks to it . It does not rebound from the barrier . In case of elastic collision , rebound creates large impulse creating huge damage to the car .

a ball of mass 1kg is being suspended 10m above the ground & is then dropped. what is the balls kinetic energy just before it hits that ground ?

a. 10 J
b. 98 J
c. 50 J
d. 0 J

Answers

Answer:

E = 98 J

Explanation:

Given that,

The mass of a ball, m = 1 kg

It is being suspended 10m above the ground & is then dropped.

We need to find the ball's kinetic energy just before it hits that ground. The conservation of energy holds here. It means, the kinetic energy just before it hits that ground is equal to its potential energy i.e.

[tex]E=mgh\\\\E=1\times 10\times 9.8\\\\E=98\ J[/tex]

so, the required energy is 98 J. Hence, the correct option is (b) "98 J".

A 13.0km bucket is lowered vertically by a rope in which there is 170N of tension at a given instant. Determine the magnitude of the acceleration of the bucket. Is it up or down?

Answers

Answer:

13.07m/s2 down

Explanation:

I think the equation would be

Fnet/m=a

since tension is the only force mensioned that means that

170N/13.0kg=13.07 m/s2 down

acceleration is down

Answers

Answer:

C = 1.01

Explanation:

Given that,

Mass, m = 75 kg

The terminal velocity of the mass, [tex]v_t=60\ m/s[/tex]

Area of cross section, [tex]A=0.33\ m^2[/tex]

We need to find the drag coefficient. At terminal velocity, the weight is balanced by the drag on the object. So,

Weight of the object = drag force

R = W

or

[tex]\dfrac{1}{2}\rho CAv_t^2=mg[/tex]

Where

[tex]\rho[/tex] is the density of air = 1.225 kg/m³

C is drag coefficient

So,

[tex]C=\dfrac{2mg}{\rho Av_t^2}\\\\C=\dfrac{2\times 75\times 9.8}{1.225\times 0.33\times (60)^2}\\\\C=1.01[/tex]

So, the drag coefficient is 1.01.

Engineers at the Space Centre must determine the net force needed for a rockets engine to achieve an acceleration of 70 m/s2. Assume the rocket is in outer space with no gravitational or other forces acting on it. If the mass of the rocket is 45 000 kg, what force is required to be produced by the rocket engines?

Answers

Answer:

3,150,000N

Explanation:

According to Newton's second law;

F = mass * acceleration

Given

Mass = 45000kg

acceleration = 70m/s^2

Substitute

F = 45000 * 70

F = 3,150,000N

Hence the force required to be produced by the rocket engines is 3,150,000N

Answer:

3,150,000 Newtons

Explanation:

F=M*A

F=45,000kg times (*) 70 m/s squared

F=3,150,000N (newtons)

The speed of a wave is 70 m/s. If the wavelength of the wave is 0.4

The specific heat capacity of copper is 390 J/Kg AC. What does this
mean?

Answers

Answer:

It means that 400 J of heat is the required amount to raise or lower thh temperature of a 1kg piece of copper

Explanation:

390 J/Kg °C specific heat capacity of copper means, 390 J of energy is required to raise the temperature of 1 kg of copper by 1 °C

From the given information,

The specific heat capacity of copper is 390 J/Kg °C. To determine what this means, we will define the term specific heat capacity.

The specific heat capacity of a substance is the amount of energy required to raise the temperature of 1 kg of the substance by 1 °C.

Therefore, 390 J/Kg °C specific heat capacity of copper means, 390 J of energy is required to raise the temperature of 1 kg of copper by 1 °C.

Hence, 390 J/Kg °C specific heat capacity of copper means, 390 J of energy is required to raise the temperature of 1 kg of copper by 1 °C.
