A50-kg skier waits at the top of a 100 m high hill to ski down the hill. whats the skier’s gravitational potential energy?

Let's take the reference of zero when the skier is downhill. The skier is at a height of 100 with respect to the foot of the hill. Recall that the gravitational potential energy for a body with mass m at a height h is given by:

By plugging the values of  and  and taking  we get:

The answer is a) taiga because taigas are cold
