A ski starts from rest and slides down a 23° incline 60 m long. Use energy methods.(adsbygoogle = window.adsbygoogle || []).push({});

(a) If the coefficient of friction is 0.09, what is the ski's speed at the base of the incline?

m/s

(b) If the snow is level at the foot of the incline and has the same coefficient of friction, how far will the ski travel along the level?

m
