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 kg that is traveling horizontally at 10.8 m/s. Olaf's mass is 70.9 kg. (Figure 1) Figure A B < 1 of 1 ▼ Part C If the ball hits Olaf and bounces off his chest horizontally at 7.10 m/s in the opposite direction (ouch!), what is his speed up after the collision?
