Question

In a particular crash test, a car of mass 1 500 kg collides with a wall as shown in Figure 9.5. The initial and final velocities of the car are ν^→_i = 215.0î m/s and
ν^→_f = 2.60î m/s, respectively. If the collision lasts 0.150 s, find the impulse on the car during the collision and the average net force exerted on the car.

Figure 9.5 (Example 9.3) (a) This car's momentum changes as a
result of its collision with the wall. (b) In a crash test, much of the
car's initial kinetic energy is transformed into energy associated
with the damage to the car.
