Question

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 1

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.
