A boy weight 360N runs up a flight of stairs consisting of 20 steps each 10cm high in 10 second what is power
To find the power exerted by the boy while running up the stairs, we need to use the formula for power:
Power = Work / Time
First, let's calculate the work done by the boy while running up the stairs. The work is given by the formula:
Work = Force x Distance
The force exerted by the boy is equal to his weight, which is given as 350 Newtons. The distance is the total height covered while climbing the stairs, which is calculated as:
Distance = Number of stairs x Height of each stair
Given that there are 20 stairs and each stair is 16 centimeters high, we convert the height to meters:
Height = 16 centimeters x (1 meter / 100 centimeters) = 0.16 meters
Now, we can calculate the total distance covered:
Distance = 20 stairs x 0.16 meters = 3.2 meters
Now that we have both the force (350N) and distance (3.2m), we can calculate the work done:
Work = 350N x 3.2m = 1120 Joules
Finally, we can calculate the power by dividing the work by the time taken:
Power = 1120 Joules / time (in seconds)
However, the time taken to climb the stairs is not given in the question. So, we cannot determine the power without the knowledge of the time taken. Please provide the time taken so that we can calculate the power.
