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 Olaf catches the ball, with what speed do Olaf and the ball move afterward?

momentum is conserved.
momentumball= momentumballandOlaf
mb*vb=(mb+mo)V
solve for V
momentumball= momentumballandOlaf
mb*vb=(mb+mo)V
solve for V

If the ball hits Olaf and bounces off his chest horizontally at 8.10m/s in the opposite direction, what is his speed vf after the collision?
Ans. mball*Vi1+molaf*Vi2=mball*Vf1+molaf*Vf2
Solve for Vf2 ( you have all the other variables given)

Side note: Since Olaf wasn't moving initially, molaf*Vi2 = 0
