A waitress shoves a ketchup bottle with mass 0.45 kg to her right along a smooth, level lunch counter. The bottle leaves her hand moving at 2.0 m>s, then slows down as it slides because of a constant horizontal friction force exerted on it by the countertop. It slides for 1.0 m before coming to rest. What are the magnitude and direction of the friction force acting on the bottle?

A cart for hauling ore out of a gold mine has a mass of 429 kg, including its load. The cart runs along a straight stretch of track that climbs a shallow 4.33° incline. A donkey, which is trudging along and to the side of the track, has the unenviable job of pulling the cart up the slope with a 399 N force for a distance of 113 m by means of a rope that is parallel to the slope but makes an angle of 15.1° with the track. The coefficient of friction for the cart's wheels on the track is 0.0161 Use g=9.81 m/s^2, and note that angle A in the image is the angle of the incline while angle B is the angle the rope makes with the track. Find the work ?dthat the donkey performs on the cart during this process. Find the work ?g that the force of gravity performs on the cart during this process. Calculate the work ?f done on the cart by friction during this process.
You are a member of an alpine rescue team and must get a box of supplies, with mass 2.80 kg , up an incline of constant slope angle 30.0 degrees so that it reaches a stranded skier who is a vertical distance 3.10 m above the bottom of the incline. There is some friction present; the kinetic coefficient of friction is 6.00×10^−2. Since you can't walk up the incline, you give the box a push that gives it an initial velocity; then the box slides up the incline, slowing down under the forces of friction and gravity. Take acceleration due to gravity to be 9.81 m/s2. Use the work-energy theorem to calculate the minimum speed v that you must give the box at the bottom of the incline so that it will reach the skier.
John is building a frictionless track with a block (? = 20.0kg) sliding on it (no flying up). The block is initially at rest at point A, and it is pulled by an external force ? = 60.0N (with an angle ? = 25.0 ° from the surface of the track) over a distance ? = 3.50 to point B. There are no external forces on the block after point B and the block continues to slide along the track until the magnitude of its velocity is ?C = 0.700m/s at point C. What is the height ℎ of point C (relative to point A)?

Consider a block being pulled from rest through a distance 46.03 cm to the right across a tabletop. A cord that provides a tension with magnitude 19.31 N is attached to the right side of the block and extends horizontally, parallel to the table. As the block slides, the force of kinetic friction between the 1.831 kg block and the table is 2.844 N. Calculate the speed of the block at the end of the 46.03 cm movement. Report to four significant figures, in standard units, but do not include the unit in the answer field.
