1. How much work is done by a constant force of 10N to pull a box across the floor over a displacement of 4.7m. Assume the force is applied in the same direction of the displacement. (draw a diagram of the situation and show all of your work)

2. Suppose the box in 1.1) has a 5kg mass. Assuming that the box slides with no friction determine the change in kinetic energy of the box after the 4.7m displacement. (show all your work)

3. Assuming that the box in 1.1) started from rest use the result in 1.2) to determine the final speed of the box (show all your work)
