The water of a 14' x 48' metal frame pool can drain from the pool through an opening at the side of the pool. The opening is about h = 1.08 m below the water level. The capacity of the pool is V= 3760 gallons, the pool can be drained in t 9.9 mins. Po is the pressure of the atmosphere. e is the density of the water

(c) both a forward and a backward force are acting on the cart, but the backward force is larger. (d) only a backward force is acting, no forward force.
