A horizontal force of magnitude 34.5 N pushes a block of mass 4.09 kg across a floor where the coefficient of kinetic friction is 0.609.

(a) How much work is done by that applied force on the block-floor system when the block slides through a displacement of 3.88 m across the floor?

(b) During that displacement, the thermal energy of the block increases by 39.3 J. What is the increase in thermal energy of the floor?
