A professional golfer is examining a video of a practice swing. The high‑speed footage shows that his club is in contact with the ball (which was initially at rest on the tee) for only Δ?=0.971 ms, and the radar gun clocks the speed of the ball as ?b=146 mph after it comes off the club. The golf ball has a mass of ?b=45.9 g. What is the magnitude of the impulse imparted to the ball by the club? What is the magnitude of the average force of contact between the club and the ball?

A tennis player receives a shot with the ball (0.0600 kg) traveling horizontally at 59.2 m/s and returns the shot with the ball traveling horizontally at 38.0 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 Your response differs from the correct answer by more than 10%. Double check your calculations. N - s direction +x (b) What work does the racket do on the ball? (Indicate the direction with the sign of your answer.)

A professional golfer is examining a video of a practice swing. The high-speed footage shows that his club is in contact with the ball (which was initially at rest on the tee) for only At = 0.971 ms, and the radar gun clocks the speed of the ball as v = 146 mph after it comes off the club. The golf ball has a mass of m, = 45.9 g. What is the magnitude of the impulse imparted to the ball by the club? magnitude of the impulse: kg ·m What is the magnitude of the average force of contact between the club and the ball? magnitude of the average force of contact:

In the overhead view of the figure, a 410 g ball with a speed v of 3.2 m/s strikes a wall at an angle e of 31° and then rebounds with the same speed and angle. It is in contact with the wall for 5.2 ms. In unit-vector notation, what are (a) the impulse on the ball from the wall and (b) the average force on the wall from the ball? (a) Number i i+ j Units (b) Number i i+ i j Units >

A ball of mass 0.180 kg is dropped from rest from a height of 1.25 m. It rebounds from the floor to reach a height of 0.730 m. What impulse was given to the ball by the floor? magnitude    kg · m/s

Consider the problem of returning a serve in tennis. A serve is hit at a speed of 73.3 m/s, and is hit back to the server with a speed of 51.1 m/s. The ball of mas m = 57 g   is in contact with the racket for 0.01s. (a) What is the magnitude of the impulse imparted to the ball as it is returned to the server? Estimate the magnitude of the average force on the ball.

A professional golfer is examining a video of a practice swing. The high-speed footage shows that his club is in contact with the ball (which was initially at rest on the tee) for only At = 0.571 ms, and the radar gun clocks the speed of the ball as Up = 176 mph after it comes off the club. The golf ball has a mass of mh = 45.9 g.

A ball falls from height of 20.0 m, hits the floor, and rebounds vertically upward to height of 15.0 m. Assume that m ball = 0.385 kg. (a) What is the impulse (in kg. m/s) delivered to the ball by the floor? magnitude x direction 979.1 Assume the only impulse delivered to the ball is from the floor, which equals the change in momentum of the ball. Find the initial and final speeds of the ball using conservation of mechanical energy, and calculate Ap noting that all the motion is in the y-direction. kg. m/s up ✓✓ (b) If the ball is in contact with the floor for 0.0300 seconds, what is the average force (in N) the floor exerts on the ball? magnitude 19.223 x Use the impulse-momentum theorem and the result from part (a) to find the force, given that the contact time interval is 0.0300 s.
