A 67.0 kg crate rests on a level floor at a shipping dock. The coefficients of static and kinetic friction are .800 and .460 respectively.

A) what horizontal pushing force is required to just start the crate moving?

B) What horizontal pushing force is required to slide the crate across the dock at a constant speed.

If anyone could please help, I would greatly appreciate it. THANK YOU!
