A horizontal force of magnitude 30.0 N pushes a block of mass 3.85 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?
b.)During that displacement, the thermal energy of the block increases by 38.0 J. What is the increase in thermal energy of the floor?
c.)What is the increase in the kinetic energy of the block?
