Inclination 34381

A skier starts down a hill of length l and an angle of inclination of 10˚. It then moves to a horizontal section of the track, which travels the same length l until it stops.
Determine the coefficient of sliding friction between the skis and the snow.

Correct answer:

k =  0.1736

Step-by-step explanation:

α=10° rad=10° 180π =10° 1803.1415926 =0.17453=π/18 g=9.81 m/s2  s1=s2=l s1=21 a1 t12 s2=21 a2 t22  a1=a2  m/s2 g sin α = g k  k=sinα=sin0.1745=0.1736
