Work Done on Stone: 0 Kinetic Energy Change

[songoku]

Homework Statement

A stone has mass 2.5 kg is placed in a liquid. It falls with constant speed 2 ms^-1 and travels 80 cm. Find the work done

Homework Equations

W = delta Ek

The Attempt at a Solution

The work done = 0 because there is no change in kinetic energy. Am I right?

Thanks

The stone is moving in liquid with terminal velocity. So the net force acting on it zero. So the work done on the stone is zero.
