A 1300-N crate rests on the floor. How much work is requred to move it at constant speed [Solved]

m

part a)
Since the problem states constant speed, the acceleration is zero. The frictional force and the force exerted on the crate by the mover are the forces acting on the crate. The work then is only

part b)
Similar to the above except vertical. The force needed to lift the crate at constant speed vertically is 1300 N. Therefore

part b)
Similar to the above except vertical. The force needed to lift the crate at constant speed vertically is 1300 N. Therefore

part b)
Similar to the above except vertical. The force needed to lift the crate at constant speed vertically is 1300 N. Therefore
