Solution for QID #20043: 1) A 0.5 kg ball moving horizontally at 10.0 m/s strikes a v | StudyHelpMe

1) A 0.5 kg ball moving horizontally at 10.0 m/s strikes a vertical well and rebounds in the opposite direction at 5.0 m/s. If the collision took place in 0.1 s, what was the magnitude of the average force on the wall? 2) You are standing on a sheet of ice that covers the football stadium parking lot in Buffalo, where there is negligible friction between your feet and the ice. A friend throws you a ball of mass 0.500 kg that is traveling horizontally at 10 m/s. Your mass is 65.0 kg. If the ball hits you and bounces off your chest elastically, what is your speed after the collision?
