A person weighing 70 kg climbs the stairs to a height of 3.5 meters, developing an average power of 0.35 kW. find the amount of time it took to climb
To determine the period of time spent by the specified person to climb the stairs, we apply the formula: t = A / N = m * g * h / N.
Constants and variables: m – the mass of the specified person (m = 70 kg); g – acceleration due to gravity (g ≈ 10 m / s2); h – ladder height (h = 3.5 m); N – average power (N = 0.35 kW = 350 W).
Calculation: t = m * g * h / N = 70 * 10 * 3.5 / 350 = 7 s.
Answer: The specified person spent 7 seconds climbing the stairs.
One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society.
