If two objects with different masses are pushing each other, which exerts the greater force?
the object with the greater mass exerts the greater force on the smaller object because the larger object has more inertia.
the object with the smaller mass exerts the greater force on the larger object because it requires more force to make the larger object move.
it is impossible to tell which object exerts the greater force unless we know which object accelerates.
they both exert the same amount of force on each other regardless of their mass, but in opposite directions.

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.)
