a) A snowboarder starts from rest and rides 31.45 m down a snow-covered slope that makes an angle of 26.45° with the horizontal and reaches the flat snow near the lift. How far will she travel along the flat snow if the coefficient of kinetic friction between her board and the snow is 0.03961?

b) A 2.95-kg block initially at rest at the top of a 3.69-m incline with a slope of 42.7° begins to slide down the incline. The upper half of the incline is frictionless, while the lower half is rough, with a coefficient of kinetic friction ?k = 0.305. How fast is the block moving at the bottom of the incline?
