A 0. 50 kg ball traveling at 6. 0 m/s due east collides head on with a 1. 00 kg ball traveling in the opposite direction at -12. 0 m/s. After the collision, the 0. 50 kg ball moves away at -14 m/s. Find the velocity of the second ball after the collision.

A200-n force is applied to the foot-operated air pump. the return spring s exerts a 2.6-n·m moment on member oba for this position. determine the corresponding compression force c in the cylinder bd. if the diameter of the piston in the cylinder is 40 mm, estimate the air pressure generated for these conditions. state any assumptions. enter a positive number for the compression force c.
