Babe Ruth steps to the plate and casually points to left centerfield to indicate the location of his next home run. Themighty Babe holds his bat across his shoulder, with one handholding the small end of the bat. The bat is horizontal, andthe distance from the small end of the bat to the shoulder is22.5cm. If the bat has a mass of 1.1kg and has a center ofmass that is 67vm from the small end of the bat, find the magnitudeand direction of the force exerted by: a) the hand
b) the shoulder.

Suppose water is leaking from a tank through a circular hole of area ah at its bottom. when water leaks through a hole, friction and contraction of the stream near the hole reduce the volume of water leaving the tank per second to cah 2gh , where c (0 < c < 1) is an empirical constant. a tank in the form of a right-circular cone standing on end, vertex down, is leaking water through a circular hole in its bottom. (assume the removed apex of the cone is of negligible height and volume.) (a) suppose the tank is 20 feet high and has radius 8 feet and the circular hole has radius 2 inches. the differential equation governing the height h in feet of water leaking from a tank after t seconds is dh dt = − 5 6h3/2 . if the height of the water is initially 8 feet, how long will it take the tank to empty? (round your answer to two decimal places.)
