A horizontal force of magnitude 33.5 N pushes a block of mass 3.80 kg a distance of 3.00 m across a floor, where the coefficient of kinetic friction is 0.600.
(a) How much work is done by that applied force on the block-floor system?
Work done is force x distance, regardless of what the mass and friction is.
The answer is 33.5 * 3.00 = 100.5 Joules
