The vertical wall of a small dam is 26 m long and it holdsback a body of water that is 5.7 m deep. (Hint: Recall themethod used to calculate the center of mass of a non uniform objectin chapter of Momentum and its conservation).
(a) Calculate the force acting on the wall due to the pressureof the water. Enter scientific notation as 1.23E4.
(b) Determine the effective point of action of this force.
