Solving Ski Slope Friction: Find Speed & Distance

[Sportsman4920]

A ski starts from rest and slides down a 23° incline 60 m long. Use energy methods.
(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

Set up a conservation of energy system. PE at the top equals KE at the bottom plus energy transferred due to friction. Find the work done by friction to find the final kinetic energy

It just doesn't seem like there is enough information to figure this out, don't you need the weight of the skier?

I think when you set up the formula, the masses will factor out. Try it.
