A 1100 kg car strikes a wall with a force of 4000 N in 0.35 seconds. What is the change in the velocity of the car?

(v-u) = 1.27 m/s

Explanation:

Given that,

Mass of a car, m = 1100 kg

Force with which the wall strikes, F = 4000 N

Time, t = 0.35 s

We need to find the change in velocity of the car.

The net force acting on the car is given by :

F = ma

a is acceleration

(v-u) is the change in velocity. Hence, the change in the velocity of the car is 1.27 /s.
