The Power Output of a Student Climbing Stairs

What is the power output of a student who weighs 500N and climbs the stairs from the first floor to the third floor, 15m above, in 20s? To find the power output in this scenario, we need to calculate the work done by the student in climbing the stairs and then divide it by the time taken. Let's break down the calculation:

Calculating Power in Climbing Stairs

Work Done:
To calculate the work done in climbing the stairs, we can use the formula:
Work (W) = Force (Weight) x Distance (Height climbed)

Given Data:
Force (Weight) = 500N
Distance (Height climbed) = 15m

Calculating Work Done:
W = 500N x 15m = 7500 Joules (J)

Calculating Power Output:

Power Formula:
Power (P) = Work done (W) / Time taken (t)

Given Time:
Time taken = 20 seconds

Calculating Power Output:
P = 7500 J / 20 s = 375 Watts (W)

Therefore, the power output of the student climbing the stairs is 375 Watts.
