Answer to Question #50081 in Mechanics | Relativity for prack
Question #50081
This question refers to: Laws of motion
A rubber ball of mass 0.12 kg moving at a speed of 25 m/s perpendicular to a smooth vertical wall, rebounds from the wall without loss of speed in an impact lasting 0.004 s
Calculate the change of momentum of the ball.
Give your answer in kg.m/s
Tip: consider the change of direction of the velocity before and after impact in your calculation. The answer could be a negative value.
