Two identical cars A and B are at rest on a loading dock with brakes released. Car C, of a slightly different style but of the same weight, has been pushed by dockworkers and hits car B with a velocity of 4 m/s. Knowing that the coefficient of restitution is 0.8 between B and C and 0.5 between A and B, determine the energy lost as a result of the series of collisions. (Round the final answer to three decimal places.)

A package of mass 19.81 kg is released from rest at a warehouse loading dock and slides down a 4.37-m-high frictionless chute to a waiting truck. Unfortunately, the truck driver went on a break without having removed the previous package, of mass 42.89 kg, from the bottom of the chute. Suppose the packages stick together. (a)What is their common speed after the collision? (b)Suppose the collision between the packages is elastic. To what height does the package of mass 19.81...

2- Two identical billiard balls may move freely on a horizontal table. Ball A has a velocity of 0.4 m/s as shown, and hits ball B, which is at rest, at point C defined by ? = 40° (the line of impact is along 40° path with respect to the horizontal direction). Assuming no friction, and knowing the coefficient of restitution between the two balls is 0.75, determine the velocity of each ball after impact.
