M R F Suppose you are hanging out in your childhood tree house, which has a trapdoor with a weight on top of it. Your friend climbs up to the tree house and exerts a force F directly upwards at a distance R from the pivot. What is the closest distance from the pivot that you can place a weight of mass M to keep your friend out of the tree house?

Starting from rest, a 93-kg firefighter slides down a fire pole. The average frictional force exerted on him by the pole has a magnitude of 840 N, and his speed at the bottom of the pole is 3.6 m/s. How far did he slide down the pole? ho

Power As shown in the picture below, you and a friend are pushing a box horizontally. You can assume that you and your friend are both pushing completely horizontally in this case. Your combined push force (from you and your friend) is Push = 46.0 N. The box has a mass of 20.0 kg. You and your friend push the box a horizontal distance of 6.50 m. There is a force of friction between the ground and the box with a value of f = 28.0 N. Assume that initially the box is at rest when you and your friend start pushing it. What is the rate at which all of the forces do work on the box? This is another way of asking about Power. You'll need acceleration to find the time - but you have enough information to calculate the acceleration.
