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...

On the Apollo 14 mission to the moon, astronaut Alan Shepard hit a golf ball with a 6 iron. The acceleration due to gravity on the moon is 1/6 of its value on earth. Suppose he hits the ball with a speed of 21 m/s at an angle 25 above the horizontal. Part A You may want to review (Pages 86 - 90). How much farther did the ball travel on the moon than it would have on earth? Express...

A 0.060-kg tennis ball, moving with a speed of 5.0 m/s, has a head-on collision with a 8.0x10-2-kg ball initially moving in the same direction at a speed of 2.4 m/s. Part A Assuming a perfectly elastic collision, determine the speed of each ball after the collision. Enter your answers numerically separated by a comma.

Part A A major league pitcher throws a baseball with a speed of 162 kilometers per hour. If the baseball weighs 195 grams and its heat capacity is 1.7 J.g-. K-, calculate the temperature increase of the ball when it is stopped by the catcher's mitt. Assume that no heat is transferred to the catcher's mitt and that the catcher's arm does not recoil when he catches the ball. Express the temperature in kelvins to two significant figures.
