A 33.0 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. Part A What are the coefficient of static and kinetic friction between the crate and the floor? Enter your answers numerically separated by a comma. Submit Request Answer Part B What push must you exert to give it an acceleration of 1.10 m/s2 ? Express your answer with the appropriate units. Part C 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/s2. What magnitude push would cause it to move? Express your answer with the appropriate units. Submit Request Answer Part D What would its acceleration be if you maintained the push in part B ?

A long, horizontal wire AB rests on the surface of a table and carries a current I. Horizontal wire CD is vertically above wire AB and is free to slide up and down on the two vertical metal guides C and D (the figure (Figure 1)). Wire CD is connected through the sliding contacts to another wire that also carries a current I, opposite in direction to the current in wire AB. The mass per unit length of the wire CD is λ. Figure 1 of 1 Part A To what equilibrium height h will the wire CD rise, assuming that the magnetic force on it is due entirely to the current in the wire AB ?
