A diagram of the front steering system of a bicycle is shown.
 

1. A rider leans forward so that 55% of their mass is exerted as a force, as shown in the diagram. A turning moment of 132.19 Nm is generated about the front axle.
2. What is the mass of the rider?   (3 marks)

2. In overcoming the resistance due to gravity, drag and rolling resistance, a rider applies a force of 500 N on the pedals. This allows the rider to cover, in 5 seconds, a distance of 20 metres from the starting point.
3. How much power was produced by the rider?  (2 marks)
