a). If I weigh 215lbs on earth, how much would I weigh (in pounds) on the moon where the acceleration due to gravity is 1.625 m/s2.
b). A horizontal force of 86.7 N is applied to a 50.5 kg crate on a rough, level surface. If the crate accelerates at 1.03 m/s2, what is the coefficient of kinetic friction between the crate and then surface?

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...
