You guys already go the answer but..oh well... F= (p2- p1)/∆t Since the ball is in opposite direction, it implies that F= (p2+p1)/∆t p2+p1 = 25* 0.02 = 0.5 Since the ball has the same mass the velocity before hitting the plate will be higher than the velocity after it bounces. So, therefore, p1... -
