Question

Amy Steak, a 52-kg woman exercised on a Monark cycle ergometer,

pedaling at a 77 rpm against a 2.5 kp resistance for 30 minutes.
Her average steady-state VO2 was 1.55 LO2min-1 and VCO2 was 1.15
LCO2�

Answer 1

The power output for the woman can be calculated using the work-energy principle.

Step-by-step explanation:

The power output for a 60.0-kg woman who runs up a 3.00 m high flight of stairs in 3.50 s can be calculated using the work-energy principle.

First, we can determine the gravitational potential energy gained by the woman: PE = mgh. Next, we can determine the work done by the woman to reach her final speed (v) using the equation: W = (1/2)mv^2. Finally, we can calculate the power using the equation: Power = Work / Time. By plugging in the given values, we can find the power output.
