# Collision of Parked Car

A car with a mass of 2,200 kg traveling at a velocity of 20 m/sec collides with a parked car. After the collision its velocity is +10 m/sec. If the mass of the parked car is 1,200 kg, determine:

(a) Speed of the parked car after the collision.

(b) Average force exerted on the parked car if the collision time (delta t) =0.1 sec.

(c) Total momentum after collision

#### Solution Preview

A: 18.33 m/s.

2,200 * 20 = 2,200 * 10 + 1,200 * V2

V2 = 22,000/1,200 = 18.33 m/s.

B: 220,000 N.

F = ...

#### Solution Summary

This solution looks at the speed, force and momentum variables due to a collision.
