Why is the following situation impossible? the object of mass m = 4.00 kg in figure p6.10 is attached to a vertical rod by two strings of length ℓ = 2.00 m. the strings are attached to the rod at points a distance d = 3.00 m apart. the object rotates in a horizontal circle at a constant speed of v = 3.00 m/s, and the strings remain taut. the rod rotates along with the object so that the strings do not wrap onto the rod. what if? could this situation be possible on another planet?

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.)
