Hi, I just recently started learning physics and am stuck on this question:
You are a member of an rescue team and must project a box of supplies, with mass m, up an incline of constant slop angle theta so that it reaches a stranded hiker who is a vertical distance h above the bottom of the incline. The incline is slippery, but there is some friction present, with kinetic friction coefficient u_k. Use the work-energy theorem to calculate the minimum speed v (in terms of m, g, h, u_k and theta) that you must give the box at the bottom of the incline so that it will reach the hiker.
I took the forces into consideration and used a coordinate system in line with the direction of friction and the normal force. The forces that I believe are on it are friction, normal force, weight downwards and the force used to push the box. I just cant seem to get a final answer.
Any help will be greatly appreciated.
