A tennis ball moving with velocity 20 m s-1 towards a racquet. The ball is struck by the racquet so that it moves back in the opposite direction at 30 m s-1. If the racquet remains in contact with the ball for 0.02 s, find the average acceleration impacted by the racquet onto the tennis ball.
The answer : -2500 ms-2β

Suppose that two tanks, 1 and 2, each with a large opening at the top, contain different liquids. a small hole is made in the side of each tank at the same depth 1.57 m below the liquid surface, but the hole in tank 2 has 2.49 times the cross-sectional area of the hole in tank 1. (a) what is the ratio Ο1/Ο2 of the densities of the liquids if the mass flow rate is the same for the two holes? (b) what is the ratio rv1/rv2 of the volume flow rates from the two tanks? (c) at one instant, the liquid in tank 1 is 14.9 cm above the hole. if the tanks are to have equal volume flow rates, what height above the hole must the liquid in tank 2 be just then?
