The mass of a regulation tennis ball is 57 g (although it can vary slightly), and tests have shown that the ball is in contact with the tennis racket for 30 ms. (This number can also vary, depending on the racket and swing.) We shall assume a 30.0 ms contact time. One of the fastest-known served tennis balls was served by “Big Bill” Tilden in 1931, and its speed was measured to be 73 m/s. Suppose that the positive direction...

A golf ball (50 g) hit by a club is accelerated from rest to 50 m/s in 2.50 ms. What are the magnitudes of the impulse delivered to the ball and the average force acting on the ball? Impulse = Average Force = A disk of radius 10.0 cm spins about an axis through its center at a constant 5.0 rad/s. What is the linear velocity, centripetal and tangential accelerations of a point on its rim? linear velocity = centripetal...

A tennis ball of mass 0.0600 kg is initially moving horizontally with a speed of 25.0 m/s. A tennis player hits it with his racket with an average force of 66 N, sending the ball back in the opposite direction with a speed of 35.0 m/s. For how much time was the racket and ball in contact, in units of seconds?

a tennis ball was hit with a tennis racquet. The ball was hit in
the same direction from which it approached the raquet ( the
opposite of the direction it was going), so it was s essentially a
one- dimensional collision. The 60.0 gram tennis ball approached
the racquet with a speed of 34.3 m/s. The tennis racquet gave the
ball an impulse of 4.5 newton-seconds. a) Find the velocity of the
ball after the collision.

A tennis ball has mass 0.055kg and is hit at a speed of 120km/h by the server. The opposing player hits the ball exactly back along the line of its trajectory giving the ball a new speed of 110km/h. If the contact time between the racquet and the ball is 0.015s what is the average force on the tennis ball imparted by the opposing player. 234N 843N 10.2N 36.7N 122N

3. A ping-pong ball is a hollow sphere that has a radius of 0.100 m and a mass of 0.00270 grams. At one point during a game of table tennis the ball is initially rotating at 100 rad/s counterclockwise (around its center of mass) before being hit by a paddle. The hit from the paddle changes the angular velocity to 60 rad/s clockwise in a time of 0.200 seconds. (a) Through how many radians will the ball turn...
