A(n) 92 kg clock initially at rest on a horizontal floor requires a(n) 647 N horizontal force to set it in motion. After the clock is in motion, a horizontal force of 527 N keeps it moving with a constant velocity. The acceleration of gravity is 9.81 m/s2.
a) Find µs between the clock and the floor.
b) Find µk between the clock and the floor.
