A ski starts from rest and slides down a 22° incline 75 m long. (a) If the coefficient of friction is 0.090, what is the ski's speed at the base of the incline? (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? Important: use energy methods to solve this problem.
a) Solve for the ski's speed at the base of the incline.
b) Determine the distance the ski travels along the level.
c) Calculate the work done by friction.
d) Find the gravitational potential energy lost by the ski.
