A 1,270-kg car traveling initially with a speed of 25.0 m/s in an easterly direction crashes into the rear end of a 9,100-kg truck moving in the same direction at 20.0 m/s (see figure below). The velocity of the car right after the collision is 18.0 m/s to the east.
(a) What is the velocity of the truck right after the collision? (Round your answer to at least three decimal places.)
(b) How much mechanical energy is lost in the collision?

A 2290 kg car traveling at 11.7 m/s collides with a 2620 kg car
that is initially at rest at the stoplight. The cars stick together
and move 3.30 m before friction causes them to stop. Determine the
coefficient of kinetic friction betwen the cars and the road,
assuming that the negative acceleration is constant and that all
wheels on both cars lock at the time of impact.
