12.53 ... CALC A swimming pool is 5.0 m long, 4.0 m wide, and 3.0 m deep. Compute the force exerted by the water against (a) the bottom and (b) either end. (Hint: Calculate the force on a thin, hor- izontal strip at a depth h, and integrate this over the end of the pool.) Do not include the force due to air pressure.
