One of the great dangers to mountain climbers is an avalanche, in which a large mass of snow and ice breaks loose and goes on an essentially frictionless "ride" down a mountainside on a cushion of compressed air. the acceleration of gravity is 9.8 m/s 2 . avalanche µ = 0 338 m 21.3 ◦ if you were on a 21.3 ◦ slope and an avalanche started 338 m up the slope, how much time would you have to get out of the way? answer in units of s.
