Question

In the crash test, the passenger compartment comes to rest in 0.20 s.

Calculate the deceleration of the passenger compartment.

Solution

To calculate the deceleration of the passenger compartment, we need to know the initial speed of the compartment before the crash. However, this information is not provided in the question.

If we had the initial speed, we could use the formula for acceleration (which is the same as deceleration, but in the opposite direction):

a = Δv / Δt

where: a is the acceleration (or deceleration in this case), Δv is the change in velocity (which would be the initial velocity, since the final velocity is 0), Δt is the change in time (which is 0.20 s in this case).

Without the initial speed, we cannot calculate the deceleration.
