Question

A 2.5 kg rock is released from rest at the surface of a pond 1.8m deep. As the rock falls, a constant upward force of 4.3N is exerted on it by water resistance. Let y=0 be at the bottom of the pond.
A) Calculate the nonconservative work, Wnc, done by water resistance on the rock when the depth of the rock below the water's surface is 1.0 m.
B) Calculate the gravitational potential energy of the system,U, when the depth of the rock below the water's surface is 1.0m.
C) Calculate the kinetic energy of the rock, K, when the depth of the rock below the water's surface is 1.0m.
D) Calculate the total mechanical energy of the system, E, when the depth of the rock below the water's surface is 1.0m.
