Problem
A 2kg block is pushed with a constant horizontal force of 20N along a rough horizontal table for 5m. The coefficient of kinetic friction between the block and the table is 0.30 (take g=10ms−2).
(i) Determine the work done by the applied horizontal force.
(ii) Determine the work done by kinetic friction.
(iii) State the work done by the normal reaction.
(iv) State the work done by the weight of the block.
(v) Calculate the net work done on the block over the 5m path.
