A downhill skier is on top of a hill at a height of 30.00 meters. How fast will he be moving when he is at level portion at the bottom of the hill?
Friction (both air and snow) is an important part of downhill skiing. The skiers do not accelerate indefinitely.
For the value of the velocity at the bottom in the absence of friction, assume the conservation-of-energy value:
V = sqrt(2 g H)
where H = 30 m and g = 9.8 m/s^2.
