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 10.4 m/s. Olaf's mass is 67.8 kg.
If the ball hits Olaf and bounces off his chest horizontally at 7.80 m/s in the opposite direction, what is his speed after the collision?
