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 = 131 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 E TOOLS x10 What is the magnitude of tht uvorugu 1vrvt VI CUnuut utween the club and the ball? magnitude of the average force of contact:

A tennis ball of mass 0.065 kg and speed of 28 m/s strikes a wall at 40 degrees angle and rebounds with the same speed at 40 degrees angle in the opposite direction. The angle is measured with respect to a line perpendicular to the wall. What is the impulse on the ball?

A volleyball with a mass of 0.269 kg approaches a player horizontally with a speed of 14.0 m/s. The player strikes the ball with her hand, which causes the ball to move in the opposite direction with a speed of 21.3 m/s. (a) What magnitude of impulse (in kg. m/s) is delivered to the ball by the player? kg. m/s (b) What is the direction of the impulse delivered to the ball by the player? O Opposite to the ball's initial velocity O In the same direction as the ball's initial velocity O Perpendicular to the ball's initial velocity O The magnitude is zero. (c) If the player's hand is in contact with the ball for 0.0600 s, what is the magnitude of the average force (in N) exerted on the player's hand by the ball? N

Two rams are fighting and run straight at each other. Ram 1 has m1 = 115 kg and an initial velocity v1 = 9 m/s. Ram 2 has m2 = 127 kg and an initial velocity v2 = -7 m/s. When they collide, they lock horns.  What impulse did Ram 1 deliver to Ram 2?
