Question

A cyclist, starting from rest, applies a horizontal force of F=127N to his bicycle, moving across flat ground for a distance of dflat=283m before encountering a hill making an angle of θ=27.1∘ with respect to the horizontal. The bicycle and rider have a combined mass of m=103.9kg. Ignore air resistance and other losses due to friction.
Part (a)
 How much work, in joules, did the rider do before reaching the hill?
Part (b)  What is the bicycle's speed, in meters per second, just before the hill?
Part (c)  If the cyclist starts coasting at the bottom of the hill, what distance, in meters, does the bike travel up the incline?
