Compute all parts of given question:
Question: A 53.0-kg crate rests on a level floor at a shipping dock. The coefficients of static and kinetic friction are 0.790 and 0.440, respectively.
Part A: What horizontal pushing force is required to just start the crate moving?
N
part B: What horizontal pushing force is required to slide the crate across the dock at a constant speed?
