A horizontal force of magnitude35.5N pushes a block of mass4.15kg 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?
_______________J
b) During that displacement, the thermal energy of the block increases by39.0J. What is the increase in thermal energy of the floor?
_______________J
(c) What is the increase in the kinetic energy of the block?
_______________J
