\fSPH3UO Power Running up Stairs Lab ation Students win health problems should not participate in this investigation Problem: What is the maximum power that a physics student, in horsepower, can develop running up stairs? Materials: physics students kilogram bathroom scales . metre stick . stopwatch Procedure: 1. Measure the mass of each physics student, in kilograms. Set up a suitable table in your notebook and start recording your data. 2. Measure the height of one step. Count the number of steps and multiply by the step height to determine the vertical height the student will rise, in metres. 3. With the stopwatch, measure the time the student takes to run up the stairs, in seconds, from a standing start. 4. Calculate the force of gravity on each student, using F-mg. Use this value of force in your work calculation. 5. Calculate the power developed in both Watts and horse power . (Note: 1hp = 746W) Questions: 1. What are the physical characteristics of the powerful students in your class; are they tall, short, strong, weak, heavy, light, or a combination of these? 2. Name a sport that a person who's fits the above physical characteristics needs to generate a lot of power to be effective. 3. Mr. Hardman puts on an 8.0 kg backpack. What effective should this have on his work and power?
