Reference no: EM13561858

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?
