Problem 5 - Collisions A train car of mass mA = 31.8 x 103 kg travels at an initial speed va = 1.58 m/s. A second train car of mass mg = 24.2 x 10° kg travels with an initial speed vg = 0.88 m/s in the same direction as the first car and in front of it. When the first car catches up with the second, they collide and stick together. a) What is the speed of the two train cars just after the collision? b) What is the total kinetic energy of the system before the collision? c) What is the total kinetic energy after the collision? d) Is the collision elastic or inelastic? VA VB

Figure P9.59a shows an overhead view of the configuration of two pucks of mass In on frictionless ice. The pucks are tied together with a string of length 1' and negligible mass. At time t = 0, a constant force of magnitude F begins to pull to the right on the center point of the string. At time t, the moving pucks strike each other and stick together.
