Work & Power
In Lab 5, please review Chapter 6. Chapter 6 involves walking up a flight of stairs and recording your time via a stopwatch or chronograph. You will be asked to make measurements and calculations for the total time to work the flight of stairs (at least 7 steps) and the vertical height of the stairs from the bottom to the top.
Fill in the blanks in the Lab Answer Sheet.
Submit this Lab Answer Sheet using the link above.
These can be scanned and sent as pdf or picture files (e.g. tif, gif, etc.) or by any other method of your choice as long as the Answer Sheets are legible and translatable by Grantham University faculty.
The lab details follow:
Purpose: Determine your work and power as you climb a flight of stairs.
Materials: Yardstick, a stopwatch or digital/analog watch, bathroom scale, calculator, and you, the climber
Procedure:
Estimate your mass in kg (Hint: 1 kg (mass) = 2.2 pounds (weight)).
You should approach the bottom step of the stairs with a steady speed.
You are to start the time as you reach the first stair and stop the clock when you reach the top.
Do 2 trials, one where you are going at a slow climb and the second where you are going faster or running up the steps.
Observations and Data:
Calculate the work and power for you to climb the flight of stairs
Work (you) = _____; power (you) = ________
Calculate your power in kilowatts: (P(kW) = _____.
Application:
Your local electric company supplies you with 1 kW of power for 1 hour for 8 cents. Assume that you could climb these stairs continuously for 1 hour. How much money would this climb be worth? $_________.
Explanation / Answer
The price will end up near a buck per 100kg of your weight. Heavier people get more, skinny people get less.
If you weigh 70kg, you will get between $60 & $80.
