A teenager weighing 30 kg runs up the stairs and after 12 seconds reaches a height of 10 m.

A teenager weighing 30 kg runs up the stairs and after 12 seconds reaches a height of 10 m. Determine the strength of the teenager.

These tasks: m (teenager’s weight) = 30 kg; t (the duration of the teenager’s ascent up the stairs) = 12 s; h (height reached) = 10 m.

Reference values: g (acceleration due to gravity) ≈ 10 m / s2.

The power of a teenager can be calculated using the formula: N = F * V = m * g * h / t.

Let’s calculate: N = 30 * 10 * 10/12 = 250 W.

Answer: When climbing stairs, the teenager developed a power of 250 watts.
