    physics skier average power problem

    In 2.0 minutes, a ski lift raises 3 skiers at constant speed to a height of 105 m. The average mass of each skier is 65 kg. What is the average power provided by the tension in the cable pulling the lift? please help with the equation. is that in watts? W

    how fast is the skier going, using kinetic friction and length.

    A skier slides horizontally along the snow for a distance of 27 m before coming to rest. The coefficient of kinetic friction between the skier and the snow is µk = 0.050 Initially, how fast was the skier going? m/s not sure how to reach the answer with so few variables involved...
