A cat climbs up the side of a tree, tilted at a 10 degree angle relative to the vertical (the cat is on the top side). The cat's claws dig into the tree bark, which pushes the cat up the tree.  If the cat has a mass of 5 kg, how hard does it have to push into the tree in order to climb up at constant speed?

A 120 lb., 55-year-old female lifts a box with weight of 18 pounds from a position on the floor to a conveyor whose surface height is 25 inches from the floor. She lifts this box at a rate of four lifts per minute. The box, which has cutout handles at a distance of 7 inches from the floor, begins in a position 45 degrees to the right at a distance of 12 inches and ends directly in front of her at a forward distance of 18 inches. The worker performs this task constantly for 6 hours per day. Calculate the FIRWL and FILI for the start position.

Find the work done in pushing a car along a level road from point A to point B, 80 feet from A, while exerting a constant force of 95 pounds. Round to the nearest foot-pound.

A cylindrical tank half full of water is lying on its side. If the radius of the tank is 1m and the length is 2m, find the force against the end. Sketch the situation.

Visitors to the top of the Empire State Building, which is 1,250 feet high, are cautioned not to throw objects off the roof. How much damage could an object of mass 1 oz. dropped from the roof do?

A spy stands on the sidewalk by an apartment building examining a foreign embassy across the street. The spy then climbs 30 m to the top the building and then slides 40 m along a wire at a 20° angle below horizontal to reach a window on the embassy. What is their total displacement from the sidewalk to the embassy window?

A box of mass m=3.0kg slides down a smooth incline plane of 5.0m long with angle. Please find the speed when the box slides to the bottom of this incline. We assume the box starts to slide at rest.
