You swing a bat and hit a heavy box with a force of 1500 n. the force the box exerts on the bat is
a. less than 1500 n if the box moves.
b. greater than 1500 n if the box moves.
c. greater than 1500 n if the bat bounces back.
d. exactly 1500 n only if the box does not move.
e. exactly 1500 n whether or not the box moves.

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.)
