In a particular crash test, a car of mass 1500 kg collides with a wall as shown in Fig. The initial andfinal velocities of the car are v=-15.0ms' and 7; =-5.00; ms', respectively. If the collisionlasts 0.150 s, find the impulse caused by the collision

Answer:
Force= ma
= m(v-u)/t
=1500(15+5)/0.15
=150000*20/15
F=2,00,000N
The collision creates an impulse of 2,00,000 Newton.
