Devin Seese 3409531 Joe Kinney Problem 5: Power And The Human Body Problem Description: In this problem, Nic proceeded up a flight of stairs in three variable speeds: walking, jogging, and sprinting. The time to climb the stairs was recorded each time and his heart rate was also calculated once at the top. This problem investigates mechanical power produced from a human body, and the maximum power that can be produced for the situation. First, predictions were made in regards to the maximum power a human body could produce from the given situation and a graph comparing power output and heart rate was created. Second, Nic’s resting heart was calculated, his mass was acquired, and the height of the steps was measured. Third, the three trial runs were conducted and timed, his heart rate was calculated, and the data was recorded. Finally, the data was plugged into the equation and human power for each scenario was found. Error could have occurred when the height of the stairs was calculated. Human error could have also occurred when finding the time it took him to climb the stairs and while taking his heart rate. The lab required a stopwatch, a meter stick, a scale, and a way to find heart rate.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
