A crate of 37.2-kg tools rests on a horizontal floor. You exert a gradually increasing horizontal push on it and observe that the crate just begins to move when your force exceeds 322 N . After that you must reduce your push to 240 N to keep it moving at a steady 29.1 cm/s . A.What is the coefficient of static friction between the crate and the floor? B.What push must you exert to give it an acceleration of 1.11...

suppose you have a 113 kg wooden crate resting on a wood floor. first determine the maximum force can you exert horizontally on the crate without moving it. Then if you continue to exert those force once the crate starts to slip, what will it acceleration then be? The coefficient of static friction is 0.5, the coefficient of kinetic friction is 0.3 for a wooden crate on a wooden floor
