You want to push a 66-kg box up a 30° ramp. The coefficient of kinetic friction between the ramp and the box is 0.35. With what magnitude force parallel to the ramp should you push on the box so that it moves up the ramp at a constant speed?

    You have to overcome friction and gravity

    gravity down the plane:mg*SinTheta
    friction: mg*mu*cosTheta

    add them.
