A driver traveling at 43 m/s in a car of mass
990 kg runs into the rear end of a police
car of mass 1400 kg, traveling at 30.53 m/s.
The collision is completely inelastic, and all
motion is restricted to a straight line.
The acceleration of gravity is 9.8 m/s2 .
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
0.4. 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.
