A skier is pulled up a slope at a constant velocity by a tow bar. The slope is inclined at 27.2 ° with respect to the horizontal. The force applied to the skier by the tow bar is parallel to the slope. The skier's mass is 53.7 kg, and the coefficient of kinetic friction between the skis and the snow is 0.137. Find the magnitude of the force that the tow bar exerts on the skier.
The physics profs aren't on right now but I'm sure they will be along shortly. Sorry I can't help. You may wish to repost using just "physics" in the subject line without my name. That will assure you that they will see your post as soon as they are on-line.
thanks
