Question

An object of mass m which is hang (by means of a string of negligible mass) at the surface

of a reservoir of water placed on the ground. Assuming that the reservoir is of depth D and

the object released to fall vertically downward. Derive the equations of motion of the object

assuming that the resistance offered by the water is R Newtons. How much time is need to

get the object to the bottom of the reservoir? With appropriate choice of parameters, plot

the potential energy of the object as a function of time.​
