A conservative force F is in +x-direction and has a magnitude F(x)=3.00/(x+0.080)4 N. Let U(x) approach 0 when x approaches infinity. An object with mass 5.00 kg is released from rest at x = 0 and moves in the +x-direction. If F is the only force action on the object, what is the object's speed when it reaches x = 0.500 m?

A bicyclist starting from rest applies a force of F = 239 N to ride his bicycle across flat ground for a distance of d = 210 m before encountering a hill making an angle of θ = 17 degrees with respect to the horizontal. The bicycle and rider have a mass of m = 120 kg combined. In this problem, you can ignore air resistance and other losses due to friction.How much work, W in joules, did the rider do before reaching the hill? What is the bicycle's speed, v in m/s, just before the hill? If the cyclist starts coasting at the bottom of the hill, what distance, di in meters, does the bike travel up the incline?
