Complete the sentences correctly. Stunt car A and stunt car B are identical cars with the same mass of 34.5 kg. They are both traveling at 38.9 m/s. Stunt car A crashes into a hard wood wall, whereas stunt car B crashes into a giant bouncy net. They both come to a complete stop after the impact. Stunt Car A experiences a over a of time. Stunt Car B experiences a over a of time. Because of the force experienced by Stunt Car A, it will sustain damage than Stunt Car B.

Explanation:

Both car have the same mass

M1 = M2 = M = 34.5kg

They are also traveling at the same speed of.

V1 = V2 = V = 38.9m/s

They two car will have the same impact impulse impact on the object they hits

The impulse of the car is equal to the change in momentum

Since the body comes to rest after the impact, the final velocity is 0. And the initial velocity is v = 38.9m/s

I = ∆mv

I = mv-mu

I = 0 - 34.5 × 38.9

I = -1342.05 Ns

From newton third law, for every action, there is equal and opposite reaction, then, the cars will also receive an equal reaction of 1342.05 Ns from the object they hit

Car A experiences a 1342.05 Ns impact over a period of time

Also,

Car B experiences a 1342.05 Ns impact over a period of time

From impulse formula

I = Ft

F = I / t

It is normal for car B that hit the wood come to halt after small time,

Since it will come to halt at smaller time then, the force will be higher than that

Of car B.

Since F = I / t, the impulse Is the same for both car.

then, this shows that car A will receive more force damage than car B.

the ima (higher than 1m) will be greater than the ima with the height of 1m.
