-Explain what the box is doing at the start of the problem... Use concepts from Kinematics (motion, velocity, displacement, vectors, etc), use concepts from Forces (Newton's laws, Friction, etc.), and use concepts from Energy (Work, Mechanical, Conservation, etc). Show you know what is causing the box to move and how it is moving by discussing as many physics concepts as you can.

- Explain what the box is doing after it is pushed from the cliff... again, use the concepts you learned from Kinematics, Forces, and Energy.

- Don't forget to use diagrams, graphs, and FBDs for each part of the box's journey.

- To fully explain the motion, you will need to calculate stuff... like velocities, forces, and energy. Yes, this is a vector problem, so be sure to include directions too.

Question: Jimmy is pushing a box off of a cliff. The box has a mass of 25kg, the cliff is 75m tall, and the coefficient of kinetic friction between the box and the ground is 0.33. The box is 12m away from the edge when he starts accelerating it. After he has pushed it for 9.0m, it has a speed of 8m/s. What happens to the box?
