A man is playing tennis game. He hits a stationary ball of mass 50 g with his racquet. Interpret the energy conversions taking place when he hits ball with racquet. The average force acting on it is 600 N, so that the ball moves with a velocity of 60 m/s .Can you predict the time of hit of the ball when it leaves the racquet using given data? How can you find the change in kinetic energy of moving ball? If the ball velocity is decreased to 3⁄4 of original value due to air friction, predict the change in its kinetic energy in air compared to original value.

1) A 0.490 kg soccer ball is kicked and hits a 2.45 kg stationary tether ball hanging from a 1.49 m tether resulting in a perfectly elastic collision. If the tether ball swings out at a maximum angle of 45.4°, what was the soccer ball's velocity before the collision? 2) A 5.27 g pellet is shot horizontally from a BB gun at a speed of 15.2 m/s into a 21.1 g wooden block. The wooden block is attached to a...

While playing basketball, a batter hits the ball as it crosses home plate and gives it an initial velocity of 45m/s and launches it an angle of 19 degree above the horizontal (x-axis). The outfield wall is located 115m away from the home plate and is 3m high. The batter hits the ball when it is 1m above home pate. Part A: Find the equation describing the position and velocity of the ball as function of the Part B: Does...

A billiard ball of mass 0.28 kg hits a second, identical ball at a speed of...

A billiard ball of mass 0.28 kg hits a second, identical ball at a speed of 7.2 m/s and comes to rest as the second ball flies off. The collision takes 250 μs. a. What is the average force on the first ball? Express your answer with the appropriate units. Enter positive value if the force is along the first ball's initial speed and negative value if the force is opposite to the first ball's initial speed. b. What is...

9. A cue ball traveling at 0.65 m/s hits the stationary 8-ball, which moves off with a speed of 0.22 m/s at an angle of 40° relative to the cue ball's initial direction. Assuming that the balls have equal masses and the collision is inelastic, what will be the speed of the cue ball?

Two friends are playing golf. The first friend hits a golf ball on level ground with an initial speed of 43.5 m/s at an angle of 32.0° above the horizontal . (a) Assuming that the ball lands at the same height from which it was hit, how far away from the golfer, in meters, does it land? Ignore air resistance. (b) The second friend hits his golf ball with the same initial speed as the first, but the initial velocity...

When serving, a tennis player hits the ball horizontally. With a speed of 29.12 m/s. What minimum height, H (in m) from which the ball must be launched to just clear the 0.90 m high net about L = 17.65 m from the server. How far from the end of the service box (which is a distance of S = 6.80 m from the net) will the ball land if it just clears the net? Use the positive direction if...

1. A billiard ball moving at 5.80 m/s strikes a stationary ball of the same mass. After the collision, the first ball moves at 4.81 m/s at an angle of 34.0° with respect to the original line of motion. Assuming an elastic collision (and ignoring friction and rotational motion), find the struck ball's velocity after the collision. (a)magnitude_____ m/s (b) direction_____ ° (with respect to the original line of motion) 2. A rod of length 36.00 cm has linear density...
