Question: A 61.7-kg crate rests on a level floor at a shipping dock. The coefficients of static and kinetic friction are 0.764 and 0.425, 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 want help to find what horizontal pushing force is required to just start the crate moving.
