consider two balls A and B having the same masse. Initially, the ball B is at rest and the ball A is moving with the speed ?? = 3.00 ?/? in the +? direction as seen in the figure. After the ball A hits (or collides with) the ball B, they are both observed to move off at 45° to the x axis, ball A above the x axis and ball B below. So ?′A= 45° and ?′B = −45°. 1- What are the speeds of the two balls
