Question

Stunt car A and stunt car B are identical cars with the same mass of 47.1 kg. They are both traveling at 89.3 m/s. Stunt car A crashes into a hard concrete wall, whereas stunt car B crashes into a large pile of soft sand. 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.

Answer 1

1) HIGH IMPULSE, SHORT INSTANT

2) SMALL IMPULSE, MORE INSTANT OF TIME

more

Step-by-step explanation:

Let's propose the solution of this exercise, let's use the relationship between momentum and momentum

I = Δp

F t = m v_f - m v₀

indicates that the carriage stops v_f = 0

F t = - m v₀

Therefore, if the impact time decreases, the force must increase and therefore the damages also

Car A collides with a concrete wall that is rigid, therefore the collision occurs in a very short time, car B collides with area, so the collision time is extended, now we can complete the sentences

1) Stunt Car A experiences a _HIGH IMPULSE_ over a SHORT INSTANT__ of time.

2)Stunt Car B experiences a _SMALL IMPULSE_____ over a _MORE INSTANT__ of time.

3) Because of the force experienced by Stunt Car A, it will sustain __MORE____ damage than Stunt Car B.a

3) more
