Two cars weighting 1500kg are made to collide with a wall. the initial and final velocities of car are 15.0m/s and 2.6 m/s respectively. If the collision lasts for 0.15s, then find the impulsive force exerted on the car

Given,
Mass= 1500kg
Initial Velocity (u) = -15.0 m/s
Final Velocity (v) = 2.6 m/s
Time= 0.15 s.
Force=?
First we will find the acceleration,
a= v-u/ t
a=2.6+ 15/0.15
a= 27.3 m/s square
To find the magnitude of the force,
F= m*a
F=1500* 27.3
F= 40,950N
Therefore, force exerted on the car is 40,950N
