1. Assuming that a
professional cyclist can work at a steady rate of 500 watts, find approximately
how fast he can go on level ground.
State your assumptions. If a normal person can work at 200 watts, what
cycling speed does that correspond to?
Can you come up with any estimate of how fast a professional swimmer
should be able to swim?
