Two balls of equal mass and of perfectly elastic material are lying on the floor. One of t the second ball. Both the balls after impact will move with a velocity O v O v/2 O v/4 v/B

Two particles with masses m and 3m are moving toward each other along the x axis with the same initial speeds i. The particle with mass m is traveling to the left, and particle with mass 3m is traveling to the right. They undergo a head-on elastic collision, and each rebounds along the same line as it approached. Find the filial speeds of the particles.

The balls has a glancing collision, not a head-on-collision, deflecting the second ball by 90° and sending it south at 1.50 m/s. What is the angle that the velocity of the first ball makes after the collision, with respect to the west direction?
