Question 40
F

Two identical cars are tested by driving them into a barrier at 13 m/s.

Car A does not have a crumple zone. It stops in 0.10 s.

Car B has a crumple zone. It stops in 0.40 s.

a.

[2]
b.

Calculate the deceleration of car A.

[2]
c.

Determine how many times smaller the deceleration of car B is than the deceleration of car A.
