Problem
A block is pulled along a straight horizontal track and undergoes a displacement of 4m to the right. Two constant horizontal forces act simultaneously on the block: F1=10N to the right and F2=6N to the left.
(i) Find the work done by each force separately.
(ii) Find the algebraic sum of the two works and state the physical meaning of its sign.
