A driver traveling at 58 m/s in a car of mass 1100 kg runs into the rear end of a police car of mass 1400 kg, traveling at 25.52 m/s. The collision is completely inelastic, and all motion is restricted to a straight line. The acceleration of gravity is 9.8 m/s 2 . Immediately following the collision, what is the shared velocity of the two cars? Answer in units of m/s.

The engines stop working, wheels lock up, and the coefficient of kinetic friction of the cars is 0.7. What is the magnitude of the frictional force acting on the two cars as they slide to a halt? Answer in units of N

What is the kinetic energy of the two cars immediately following the collision? Answer in units of J.

How far do the cars slide before coming to a halt? Answer in units of m.
