Now the racquet ball is moving straight toward the wall at a velocity of vị = 15.8 m/s. The ball makes an inelastic collision with the solid wall and leaves the wall in the opposite direction at vf = -10.9 m/s. The wall exerts the same average force on the ball as before. What is the magnitude of the change in momentum of the racquet ball? 6.0342 kg-m/s Submit 5) What is the time the ball is in contact with the wall? 0.05797 s Submit 6) What is the change in kinetic energy of the racquet ball?
