# Problem with forces on a ramp

## Homework Statement

A luggage handler pulls a suitcase of mass 16.3 kg up a ramp inclined at an angle 22.0^\circ above the horizontal by a force F of magnitude 147 N that acts parallel to the ramp. The coefficient of kinetic friction between the ramp and the incline is 0.264. The suitcase travels a distance 4.15 m along the ramp.

Find work done by force F, gravity, friction, the normal force, and the total work done on the suitcase.

Also, if the speed of the suitcase is zero at the bottom of the ramp, what is its speed after it has traveled 4.15 m along the ramp?

Well, since the work is the integral of the force, once i get the force i just use the fnint() function on my ti-83 to find the work...so i didn't write it out. so if i can find the correct force, the work is easy to find. but something is wrong with my forces. but thanks for being a jackass. i really appreciate your condescending attitude towards people who are just asking for help on a forum designed to help people with these sorts of things...

and just in case you need this too, here's the page where i tried to find velocity. and i even wrote out a generic integral on here so you know what i did..
