A skier, starting from rest, coasts down a mountain that makes an angle of 20.0 ° with the horizontal. The coefficient of kinetic friction between her skis and the snow is 0.163. She coasts for a distance of 13.5 m before coming to the edge of a cliff. Use the Work-Energy theorem to find her speed at the edge of the cliff.

A skier, starting from rest, coasts down a
mountain that makes an angle of 20.0 °
with the horizontal. The coefficient of
kinetic friction between her skis and the
snow is 0.163. She coasts for a distance
of 13.5 m before coming to the edge of a
cliff. Use the Work-Energy theorem to
find her speed at the edge of the cliff.
Specify your answer in SI units up to one
decimal place. Do not include units.
