A horizontal force of magnitude 31.0 Npushes a block of mass 4.10 kg a distanceof 3.00 m across a floor, where the coefficient of kinetic frictionis 0.600.
a) How much work is done by that applied forceon the block-floor system?
b) During that displacement, the thermal energy of the block increases by 44.0 J. What is the increasein thermal energy of the floor?
c) What is the increase in the kinetic energy of the block?
