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...

Why is the friction equal to the force?
A crate of mass 180 kg sits on a horizontal floor. The coefficient of static friction between the crate and the floor is 0.4, and the coefficient of kinetic friction is 0.36. You push the crate with a horizontal force of 600 N. What is the magnitude of the frictional force on the crate by the floor in this situation? [Use g = 9.81 m/s2] Incorrect 635.69 N. Incorrect 706.32 N Incorrect...

A. A crate of mass 66.8 kg rests on a level surface, with a coefficient of kinetic friction 1.49. You push on the crate with an applied force of 1,178. What is the magnitude of the crate's acceleration as it slides? Part A answer: 3.0327 m/s^2 B. Take the same crate of mass 66.8 kg and the same coefficient of kinetic friction 1.49, but now place the crate on an inclined surface, slanted at some angle above the horizontal. Now...
