A horizontal force of magnitude 36.4N pushes a block of mass 3.81 kg across a floor where thecoefficient of kinetic friction is 0.640.
(a) How much work is done by thatapplied force on the block-floor system when the block slidesthrough a displacement of 3.93 m across the floor?
(b) During that displacement, thethermal energy of the block increases by 37.2 J. What is theincrease in thermal energy of the floor?
(c) What is the increase in the kinetic energy of the block?
