Question

A 59.1 kg skier is at rest at the top of a 275 m high run. The slope is inclined at a 22.2º angle relative to horizontal. Assuming that there is no friction between the skis and the snow, how much kinetic energy does the skier have when he/she reaches the bottom of the hill?

Answer 1

$$K=mgh$$

$$K=(59.1)(9.8)(275)=159000\ J=159\ kJ$$
