The maximum speed this cyclist can travel on a level road is 14 m/s. How does cycling uphill affect the maximum speed of this cyclist? Explain your answer.

Maximum speed is lower This is because maximum power output of cyclist is constant but additional work is done against gravityGravitational potential energy of the cyclist is increasedPower in = total energy out = kinetic energy + gravitational potential energy
