-Your answer is partially correct. A horizontal force of magnitude 36.0 N pushes a block of mass 4.32 kg across a floor where the coefficient of kinetic friction is 0.596. (a) How much work is done by that applied force on the block-floor system when the block slides through a displacement of 4.53 m across the floor? (b) During that displacement, the thermal energy of the block increases by 44.9 J.What is the increase in thermal energy of the floor?...
