Question
In the crash test, the passenger compartment comes to rest in 0.20 s.Calculate the deceleration of the passenger compartment
Solution 1
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.
Solution 2
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 in this case would be deceleration because the speed is decreasing):
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 minus the final velocity), and Δt is the change in time.
Since the compartment comes to rest, the final velocity would be 0. The change in time is given as 0.20 s. So if we had the initial velocity, we could substitute these values into the formula to find the deceleration.
