A75 kg football player is gliding forward across very smooth ice at 4.6 m/s. he throws a 0.47 kg football straight forward. a) what is the player's speed afterward if the ball is thrown at 15 m/s relative to the ground? b) what is the player's speed afterward if the ball is thrown at 15 m/s relative to the player?
Answers: 1
= Mass of player = 75 kg
= Initial velocity of player = 4.6 m/s
= Mass of ball = 0.47 kg
