A ski starts from rest and slides down a 20 degree incline 100meters long. (a) if the coefficient of friction is .090, what is the 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?
I have to use the conservation of energy method. I know thatU0 + K0= U + K. I don't know how to add friction and solve for velocity. please help me urgent
