6. A tennis player strikes a tennis ball with her racket when the ball is at the uppermost point of its trajectory as shown. Just after impact, the velocity of the ball is directed at an angle of 15° above the horizontal. If the 125 gram ball is in contact with the racket for 0.02 sec, and the average impulsive force exerted by the racket on the ball is of magnitude of 200 N and directed at an angle 9°...

A 0.060-kg tennis ball, initially moving at a speed of 12 m/s, is struck by a racket. The direction of the ball is reversed and its speed is increased to 18 m/s. A high-speed video of the impact shows that the duration of the contact between the ball and the racket was 0.050 s. What is the magnitude of the average force that was exerted on the ball by the racket while they were in contact? (MAGNITUDE) A 36 N...

Please answer all four
Re - Part A 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 m. (This number can also vary, depending on the racket and swing.) We shall assume a 30.0-ius contact time. The fastest- known served tennis ball was served by "Big Bill' Tilden in 1931, and its speed was measured to be 73...

A 1-kg ball in the air has an initial velocity vo = [ -20 ] i + [ -20 ] j m/s. It falls for a total time of 1 s. Assume that positive x-values are to the right and positive y-values are upward. What is the initial momentum pi of the ball? -20 i + -20 j kg*m/s What is the impulse or change in momentum ∆p of the ball? 0 i + -10 j kg*m/s What is the final momentum pf of the ball?...

J, A falling 0.1 kg ball has a speed of 7.0 m/s just before it hits the floor and an upward speed of 5 0 ms immediately after it rebounds. The ball is in contact with the floor for 0.01 s. What is the magnitude (in N) of the average force exerted by the floor on the ball?

Suppose the mass of the ball is 60 g and it is spinning at 40 rad/s at a distance of 1.5 m from the center of rotation. The force is 1800 N and it’s applied for 2 ms. Your goal is to find the final angular speed of the tennis ball. i. What is the initial angular momentum of the tennis ball? Hint: 40 rad/s is the angular speed (?), NOT the linear speed (?). If the angular speed is...
