Question

Measure the vertical distance from the ground floor to the landing and from the landing to the 1^st floor as shown below (convert to feet). Record this value on the data sheet, column B. Note: Your stairs might not have a landing – that’s ok. Just measure the vertical height from the bottom to the top of the stairs.
1. Record your weight (pounds) in column A of the data sheet. Multiply column A and column B. Record this value in column C.
1. Measure the time it takes to walk (at a normal pace) up the stairs from the ground floor to the first floor – use the hand rail for support. Measure 3 times and calculate the average time. Record these values in column D.
2. Measure the time it takes to briskly walk (not run) up the stairs from the ground floor to the 1^st floor – use the hand rail for support. Measure 3 times and calculate the average time. Record these values in column E.
3. Calculate the power it took to walk and to hurry from the ground floor to the 1^st floor. Enter your calculation in column F and G respectively.
4. Answer the questions.
5. Email your exercise to the instructor.
