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 ? Express your answer with the appropriate units.A 33.0 kg crate of tools rests on a horizontal floor.

Starting from rest, a small block of mass m = 0.25 kg slides down an incline from a height h = 1.2 m. As it slides down, the block experiences a force of kinetic friction of constant magnitude fk = 2.1 N only over a distance L = 0.2 m, as shown in the figure. The incline is frictionless everywhere else. After reaching the bottom of the incline, the block strikes a larger block of mass M = 1.8 kg that is attached to a spring of spring constant k = 6.5 N/m. The large block was originally at rest. The blocks stick together upon impact and travel together on the frictionless horizontal surface. Assume that both blocks are subject to the regular force of gravity (g = 9.80665 m/s2). (a) Determine the speed of the small block right before it collides with the larger block. Answer: m/s (b) Determine the speed of the combination of the two blocks immediately after the collision. Answer: m/s (c) Determine the compression of the spring when the combination of the two blocks comes to rest. Answer: m
