Problem
A worker pushes a large block of stone horizontally along rough ground at a constant speed.
(a) Outline the energy transformations taking place.
(b) How does the horizontal component of the force applied by the worker compare to the kinetic frictional force between the block and the ground?
(c) Suggest why the actual force applied by the worker is larger than the kinetic frictional force between the block and the ground.
