SUMMARY
The discussion centers on calculating the vertical height of stairs climbed by a 65.0 kg student in 25 seconds with a power output of 95 watts. The energy required to climb the stairs can be determined using the formula for power, where power equals work done over time. The work done against gravity is equal to the gravitational potential energy gained, which is calculated as mass times gravitational acceleration times height. Therefore, the vertical height of the stairs can be derived from the equation: height = (power × time) / (mass × gravitational acceleration).
