Collision of a car: Speed, average force, total momentum

A car with a mass of 2200 kgm 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 1200 kgm, 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 Summary

The solution explains and shows all the formulas used to solve the problem. The speed of the parked car after the collision, the average force exerted on the parked car if the collision time and the total momentum after collision is calculated.
