A skier (m = 75 kg) is being pulled up a snowy hill by a rope that is attached to a snowmobile. The hill has an incline of = 39 above the horizontal, and the snowmobile driver is maintaining a constant tension of T = 650 N in the rope, which is parallel to the hill's surface. Friction between the skis and the snow is negligible. If the skier's speed is currently vi = 2.0 m/s, then what will be her speed 1 vf after she has traveled another d = 10 m up the hill? The symbolic answer must be written in terms of the variables m, , T , vi, d, and g, but not all of these variables may be needed
