# Calculate the power you develop by climbing evenly, slowly at first, and then quickly from the first to the second

**Calculate the power you develop by climbing evenly, slowly at first, and then quickly from the first to the second floor of the school. Get all the necessary data yourself.**

To complete this task, we need to know our mass, as well as the height of the school floor. For example, our mass is 70 kg, and the height of the floor is 3.5 m. Now we will notice how long it takes us to rise from the first to the second floor, let this time be 17 seconds. Then we use the power formula:

N = A / t = FS / t = mgS / t = 70 • 9.8 • 3.5 / 17 = 141.24 W

This is a solution to the problem for the case when we climb the stairs slowly. Now let’s calculate how much power we develop if we climb the stairs quickly. Let’s assume that the time to climb the stairs is 7 seconds. Let’s substitute this time into the power formula:

N = A / t = FS / t = mgS / t = 70 * 9.8 * 3.5 / 7 = 343 W
