OA snowboarder with a mass of 57 kg starts from rest at the top of a frictionless slope at a height of 45 m. She follows the frictionless path to reach a lowest point, then upwards to another peak. Calculate (3/K) a) Her maximum speed and where. b) The height at which her speed is half the maximum. c) Her speed at the second peak where the height is 25 m.
