A boy weighing 350N runs up a flight of stairs consisting of 20 steps each 10 cm high in 10 seconds. What is his power?

The power of the boy is calculated by the equation Power = Work/Time.

Work = Force x Distance = 350N x 2m = 700Nm

Time = 10 seconds

Power = 700Nm/10s = 70W

Did you know?

Did you know that power is a measure of how quickly work is done? In the given scenario, the boy weighing 350N runs up a flight of stairs consisting of 20 steps each 10 cm high in 10 seconds. By calculating the work done, which is equal to the force applied (in this case, the weight of the boy) multiplied by the distance traveled (the height of each step multiplied by the number of steps), we can determine his power. With the weight of 350N and the distance of 20 steps each 10 cm high, we find that the work done is 7000J (Joules). Dividing this work by the time taken, which is 10 seconds, we discover that the boy's power is 700 Watts. Power is an important concept in the world of physics, allowing us to understand the rate at which work is done and the efficiency of various processes.
