Asked by Sidiqi
                Starting from rest, a rope with a tension 30 N pulls a 2.0 kg box up a 2.0 m long, 30 degree smooth incline. What is the speed of the box at the top?
Please show steps! Thanks

    assuming no friction.
breaking weight up into components, parallel to plane, normal to plane
Fp=mg*sinTheta
Fn=mg*cosTheta
without friction, Fp is the operating up/down plane.
Net force=m*a
30N-mg*SinTheta=m*a
so solve for a.
then,
Vf^2=2*a*d solve of Vf
