- Two billiard balls, A and B, of equal mass (150 g) move at right angles and meet at the origin of an xy coordinate system. Initially, ball A is moving along the y axis at +2.0 m/s, and ball B is moving to the right along the x axis with speed +3.7 m/s. Both balls collide and after the collision, the second ball, B, moved along the positive y axis. (a) What is the final direction of ball A? (b) What are the speeds of the two balls after the collision? (c) Considering the balls to be an isolated system, what is the net impulsive force resulting from the collision if the impact lasted for 0.4 sec?
