Elise is waiting to be picked up after soccer practice and decides to kick the ball at a wall. It bounces back to her. She focuses on kicking the ball on the ground, straight at the wall so that it bounces straight back to where she kicked it from. A soccer ball's mass 0.43 kg. (a) If Elise stops the ball and then kicks it hard enough so that it is moving at 15 m/s just after she kicks it, how much momentum did her kick transfer to the ball, and is the direction of that transfer toward the wall or away from it? (b) If the ball has a speed of 15 m/s just before it hits the wall and 10 m/s just after it hits, how much momentum is transferred during the interaction of the ball with the wall, and is the direction of that transfer toward the wall or away from it? (c) What is the coefficient of restitution for the collision of the ball with the wall? (d) How much kinetic energy is transformed into heat and sound during the interaction of the ball with the wall?
