Solve the all parts of following question given below:
Question: Olaf is standing on a sheet of ice that covers the football stadium parking lot in Buffalo, New York; there is negligible friction between his feet and the ice. A friend throws Olaf a ball of mass 0.400kg that is traveling horizontally at 10.9m/s . Olaf's mass is 72.0kg.
Part A: If Olaf catches the ball, with what speed vf do Olaf and the ball move afterward?
Part B: If the ball hits Olaf and bounces off his chest horizontally at 8.00m/s in the opposite direction, what is his speed vf after the collision?
