Quick & Easy Problem: Pushing Box Up Ramp

[Tom McCurdy]

Alright I am just trying to get a concept for a problem that I am doing

If you have a horizontal force of say X pounds and you want to push a box up a ramp that has a length of L with and angle of theta. How much work would you have done if you push the box the full length of L up the ramp?

What is the magnitude and direction of the normal force? What is the magnitude and direction of the friction force? What is the magnitude and direction of the force working against gravity? What is the net force? What is the work done against friction? What is the work done against gravity? What is the work done in giving the box kinetic energy?

nevermind

sorry guys

Radian mode on the calculator instead of degree
