A 93 kg clock initially at rest on a horizontal floor requires a 614 N horizontal force to set it in motion. After the clock is in motion, a horizontal force of 510 N keeps it moving with a constant velocity.
Find μs between the clock and the floor.
Find μk between the clock and the floor.
force friction=forces above=mu*mg
614=mu*93*g solve for mu.
dynamic: you do it.
