A 130-kg (including all the contents) rocket has an engine that produces a constant vertical force (the thrust) of 1750 N. Inside this rocket, a 14.3-N electrical power supply rests on the floor. (a) Find the acceleration of the rocket. (b) When it has reached an altitude of 120 m, how hard does the floor push on the power supply? (Hint: Start with a free-body diagram for the power supply.)

A Review | Constants Part A A 57.0 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? Enter your answers numerically separated by a comma....
