A worker pushed a 19 kg block 13 m along a level floor atconstant speed with a force directed 33° below the horizontal. Ifthe coefficient of kinetic friction between block and floor was0.23, what were (a) the work done by the worker's force and (b) theincrease in thermal energy of the block-floor system?


thank you

A horizontal force of magnitude 37.7 N pushes a block of mass 3.67 kg across a floor where the coefficient of kinetic friction is 0.562. (a) How much work is done by that applied force on the block-floor system when the block slides through a displacement of 3.24 m across the floor? (b) During that displacement, the thermal energy of the block increases by 32.8 J. What is the increase in thermal energy of the floor? (c) What is the increase in the kinetic energy of the block?

A horizontal force of magnitude 30.9 N pushes a block of mass 4.38 kg across a floor where the coefficient of kinetic friction is 0.598.
