1. Measure the distance from the hanging mass to the top of the string. 2. Measure the time it takes you to raise the 0.9 kg (2 1b.) mass by rolling the string onto the dowel rod lifting the mass as you twist your hands. Record this time in the data table. 3. Repeat the procedure, only this time use the 1.3 kg (3 1b. ) mass. 4. Record the mass of the object that was lifted. 5. Calculate the force by taking the mass (in kg) that was lifted times the acceleration due to gravity (9.8 m/s=). 6. Calculate the work and power that was produced from this activity and record your data in the table below. 7. Repeat the steps above for your lab partner. Mass Force Time Work ARMS Distance Power (kg) (m) (N) (s) () (W) You - Slow You - Fast Partner - Slow Partner - Fast LEGS 8. Determine the vertical distance in meters from the first floor to the second floor. To do this, measure the height of each step and count the number of steps between the first and second floor. 9. Measure how long it takes you to walk up the stairs at a slow pace. 10. Record your mass (kilograms) and time (seconds) the data table. 11. Determine the force used on the stairs by taking your mass (kg) times the acceleration due to gravity (9.8 m/s?). 12. Repeat the procedure but this time move at a faster pace
