Aracquet ball with mass m = 0.256 kg is moving toward the wall at v = 11.8 m/s and at an angle of θ = 29° with respect to the horizontal. the ball makes a perfectly elastic collision with the solid, frictionless wall and rebounds at the same angle with respect to the horizontal. the ball is in contact with the wall for t = 0.066 s.1)what is the magnitude of the initial momentum of the racquet ball? kg-m/s2) what is the magnitude of the change in momentum of the racquet ball? kg-m/s3) what is the magnitude of the average force the wall exerts on the racquet ball? n4) ballhitswall2 now the racquet ball is moving straight toward the wall at a velocity of vi = 11.8 m/s. the ball makes an inelastic collision with the solid wall and leaves the wall in the opposite direction at vf = -7.8 m/s. the ball exerts the same average force on the ball as before. what is the magnitude of the change in momentum of the racquet ball? kg-m/s5) what is the time the ball is in contact with the wall? s6). what is the change in kinetic energy of the racquet ball? j
