Question
Calculate the useful power developed by the pupil in climbing the stairs
Answers
GPT 3.5
The useful power developed by the pupil in climbing the stairs can be calculated using the formula:
Useful power = (Force × Distance) ÷ Time
Where:
- Force is the force exerted by the pupil in climbing the stairs (in Newtons)
- Distance is the height of the stairs (in meters)
- Time is the time taken to climb the stairs (in seconds)
Let's say the force exerted by the pupil is 500 Newtons, the height of the stairs is 5 meters, and the time taken to climb the stairs is 10 seconds.
Useful power = (500 N × 5 m) ÷ 10 s
Useful power = 2500 J ÷ 10 s
Useful power = 250 Watts
Therefore, the useful power developed by the pupil in climbing the stairs is 250 Watts.
