Solve the all parts of following question:
Question: A 61.0-kg crate rests on a level floor at a shipping dock. The coefficients of static and kinetic friction are 0.760 and 0.430, respectively.
Part A: What horizontal pushing force is required to just start the crate moving?
Part B: What horizontal pushing force is required to slide the crate across the dock at a constant speed?
I need help to find what horizontal pushing force is required to slide the crate.
