Find the increase in thermal energy of block-floor system

Reference no: EM13716992

Solve the all parts of given problem:

Problem: A worker pushed a 38 kg block 9.0 m along a level floor at constant speed with a force directed 31° below the horizontal. If the coefficient of kinetic friction between block and floor was 0.20,

Part A: What was the work done by the worker's force?

Part B: Find the increase in thermal energy of the block-floor system?

I need help to find the increase in thermal energy of the block-floor system.
