An athlete in a gym applies a constant force of 50 N to the pedals of a bicycle to keep the rotation rate of the wheel at 10 rev/s. The length of the pedal arms is 30 cm. What is the power delivered to the bicycle by the athlete?

2. A mass M is suspended from a frictionless hinge on a massless stick of length b. A massless rod is held perpendicular to the first rod (making ski-lift ''T-bar'') and another mass m slides frictionlessly along the second rod.

If the mass of the counterweight increases by adding more mass, how does the force required to lift the counterweight change?
