Olaf is standing on a sheet of ice that covers the football stadium parking lot

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 11.4m/s . Olaf's mass is 65.8kg .(Figure 1) Part A 1.) If Olaf catches the ball, with what speed v_f do Olaf and the ball move afterward? Express your answer numerically in meters per second. v_f = Part B 2.) If the ball hits Olaf and bounces off his chest horizontally at 7.70m/s in the opposite direction, what is his speed v_f after the collision? Express your answer numerically in meters per second. v_f =

Explanation / Answer

a) 0.4*11.4 = (65.8+0.4)*Vf,,,,,,,, Vf=0.069 m/s,,,,,,,,b)0.4*11.4 = (65.8)*Vf - 0.4*7.7,,,,,,,,Vf=0.116 m/s
