A tennis player receives a shot with the ball (0.0600 kg) traveling horizontally at 51.4 m/s and returns the shot with the ball traveling horizontally at 33.4 m/s in the opposite direction. (Take the direction of the ball's final velocity (toward the net) to be the +x-direction.) (a) What is the impulse delivered to the ball by the racket? magnitude N.S direction -Select--- (b) What work does the racket do on the ball? (Indicate the direction with the sign of your answer.)

A ball of mass 0.165 kg is dropped from rest from a height of 1.25 m. It rebounds from the floor to reach a height of 0.920 m. What impulse was given to the ball by the floor? kg-m/s

A tennis player receives a shot with a 0.05 kg ball travelling horizontally at 40 m/s and returns the shot with the ball traveling horizontally in the opposite direction with a speed of also 40 m/s. Find  (a)  the magnitude of the impulse delivered to the ball, and (b) the average force applied/exerted on the ball if it remains in contact with racket for 0.002 sec. A.) (a) 2.0 kg m/s,                         (b) 8000 N B.) (a) 0.0  kg m/s,                         (b) 200  N C.) (a) 0.0 kg m/s,                         (b) 2000 N D.) (a) 4.0 kg m/s,                         (b) 2000 N

A golf ball is moving at speed vo to the East. After deflecting off a tree, it moves at a speed of 0.90vo in a direction which is 25° North of East. Check all the following answers which are true statements. There may be more than one correct answer! The impulse vector (delivered by the tree) has components which point North and West The ball's momentum vector has the same magnitude before and after the collision The impulse vector (delivered by the tree) points purely to the North The ball's momentum vector decreases in magnitude during the collision
