Determine the increase in the kinetic energy of the block

Reference no: EM13496501

A horizontal force of magnitude 41.5 N pushes a block of mass 4.23 kg across a floor where the coefficient of kinetic friction is 0.571.

(a) How much work is done by that applied force on the block-floor system when the block slides through a displacement of 3.33 m across the floor?

(b) During that displacement, the thermal energy of the block increases by 38.9 J. What is the increase in thermal energy of the floor?
