Problem: A bicyclist coasts down a 7.0m hill at a steady speed of 8.0m/s.
Part A: Assuming a total mass of 95kg (bicycle plus rider), what must be the cyclist's power output to climb the same hill at the same speed?
I want help to find the cyclist's power output to climb the same hill at the same speed and express your answer to two significant figures and include the appropriate units.
