SUMMARY
The power supplied by a 60.0 kg person running up a flight of stairs with a vertical distance of 4.0 m in 4.2 seconds is calculated using the formula P = W / t. The work done (W) is derived from the force (F) multiplied by the distance (d) and the cosine of the angle (Θ), where F is the product of mass (m) and acceleration due to gravity (a). The final calculation yields a power output of 560 Watts, confirming the accuracy of the solution presented.
