A skier is being pulled up a smooth 25° dry ski slope by a rope which makes an angle of 35° with the horizontal . The mass of the skier is 75kg and the tension in the rope is 350N. Initially the skier is at rest at the bottom of the slope. The slope is smooth and g = 10 ms? Find the skier's speed after 5s.
