Compute all parts of given question:
Question: A 27 kg box sits on a table. The coefficient of static friction µs between table and box is 0.31, and the coefficient of kinetic friction µk is 0.21.
Part A: What is the force required to start the box moving?
Part B: What is the force required to keep it moving at constant speed?
I need help to find the force required to keep it moving at constant speed.
