A 51.0 kg crate of tools rests on a horizontal floor. You exert a gradually increasing horizontal push on it, and the crate just begins to move when your force exceeds 313 N. Then you must reduce your push to 208 N. to keep it moving at a steady 25.0 cm/s.

What are the coefficient of static and kinetic friction between the crate and the floor?

What push must you exert to give it an acceleration of 1.10 m/s2?
