Answer:
v = 38.34 m
Step-by-step explanation:
Given that,
Mass of a skier, m = 75 kg
It falls down a 75.0 m high slope without friction, h = 75 m
We need to find the velocity of the skier at the bottom of the slope. It is based on the concept of conservation of energy. So, v is the required velocity. So,

So, the velocity of the skier at the bottom of the slope is 38.34 m.
