How fast is the rock falling when it strikes the lower cliff? (45 m/s) 2. A 2.00-kg block of ice is sliding across a frozen pond at 3.00 m/s. WebSolution. Work is said to be done when the force applied on a body makes the body move (i.e., there is the displacement of the body). For example, a man pushing a car and a cyclist while pedaling a cycle does work, but a man who tries to push a wall does not do any work as the wall does not move.
