Q. A swimming pool has dimensions 28.0 m 11.0 m and a flat bottom. The pool is filled to a depth of 2.30 m with fresh water.
(a) What is the force exerted by the water on the bottom?N down
(b) What is the force exerted by the water on each end? (The ends are 11.0 m.)N outward
(c) What is the force exerted by the water on each side? (The sides are 28.0 m.)N outward
