A 10 ft. pole weighs 30 Ibs. (of force, to be clear). It lies flat on the ground. You lift one end of the pole until it stands vertically, the other end of the pole has been braced to the ground while you lift the other end up. Once the pole is upright, the segment of length Ax at height x has been raised a vertical distance of x feet. How much work is done to raise the pole vertically?

While riding on an elevator, a person has twoforces acting on him, a normal force and a gravity force. Suppose the person has mass m is on an elevator that 1 descends a distance d. If the total work on the person is Wiotal = -mgd, what is 4 the magnitude of the normal force? Is the elevator speeding up or slowing down? The knowns in this problem are m and g.
A box with with a mass m = 2kg is being pushed up a ramp by an unknown pushing force Fp. The coefficient of static friction between the box and interface is 0.7. The coefficient of kinetic friction between the box and interface is 0.6. The incline of the ramp is 15 degrees. The velocity of the box is constant. The surface of the ramp is 12 m. What is the work done by normal force while the box is being pushed the entire length of the ramp? [ I think that it is 0 N, since the x component of normal force which is parallel to motion is 0. Is that correct?]
A pail and its contents weigh 80 lbs. The pail is attached to the end of a 100 ft rope that weighs 10 lb and is hanging vertically.
