Coefficient of kinetic friction among the ski and snow

Reference no: EM13682178

A runaway ski slides down a 250 m long slope inclined at 37 degrees with the horizontal. If the initial speed is 10 m/s, how long does it take the ski to reach the bottom of the incline if the coefficient of kinetic friction among the ski and snow is a) 0.100 and b) 0.150?
