A crate of 45.2-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 310N . After that you must reduce your push to 231N to keep it moving at a steady 25.2cm/s .

Part A: What is the coefficient of static friction between the crate and the floor?



Part B: What is the coefficient of kinetic friction between the crate and the floor?



Part C: What push must you exert to give it an acceleration of 1.13m/s^2 ? (in N)

Part D: Suppose you were performing the same experiment on this crate but were doing it on the moon instead, where the acceleration due to gravity is 1.62 m/s^2. What magnitude push would cause it to move? (in N)

Part E: What would its acceleration be if you maintained the push in part C?
