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 0.400 that is traveling horizontally at 11.3 . Olaf's mass is 71.5 kg 1-If Olaf catches the ball, with what speed do Olaf and the ball move afterward? Express your answer numerically in meters per second 2- If the ball hits Olaf and bounces off his chest horizontally at 7.50 in the opposite direction, what is his speed after the collision? Express your answer numerically in meters per second.

Explanation / Answer

Change of momentum of the ball = m . ?v = 0.4 . 19.9 = 7.96 Olaf's change of velocity will be 7.96 / 70.4 = 0.113 m/s
