Force of a Baseball Swing. A baseball has mass 0.147 kg . a) If the velocity of a pitched ball has a magnitude of 46.0 m/s and the batted ball's velocity is 53.5 m/s in the opposite direction, find the magnitude of the change in momentum of the ball and of the impulse applied to it by the bat. Express your answer to three significant figures and include the appropriate units. b) If the ball remains in contact with the...

A racquet ball with mass m = 0.252 kg is moving toward the wall at v = 18.2 m/s and at an angle of θ = 25° 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 = 0.06 s. 1) What is the magnitude of the initial momentum of the racquet...
