1) A force F pushes a box of mass m up an incline. The box moves a distance x up the incline from an initial speed v o to a final speed v . q F x a) Use the methods of Chapters 2 and 4 to solve for the quantity ½mv 2 in terms of the given variables and fundamental constants. Do not factor like terms. Kinetic friction acts on the box.

1) A force F pushes a box of mass m up an incline. The box moves a distance x up the incline from an initial speed v o to a final speed v . q F x b) Note that the quantity x sin q is the vertical distance h the box moves. Simplify your answer to (a). Kinetic friction acts on the box.
1) A force F pushes a box of mass m up an incline. The box moves a distance x up the incline from an initial speed v o to a final speed v . q F x c) Use what you’ve learned this week to label each term in your answer using the format “________ is the change in the ________”. Kinetic friction acts on the box.

ground to a height h = 10 m above the ground at a speed of 1 mm/year. Then you release the box from rest so that it falls down into a pit that is 5 m deep…its bottom is 5 m below ground level.
