Question 420 pts
CALCULATE THE ACCELERATION OF GRAVITY TIME FOR THE MASS.
Procedure from the Lab Worksheet (Just FYI)
1. From the above six tave calculate six accelerations a.
2. Then find the gravity g from each a.
3. Take the average value of the above six values of gravity which is your final experimental g.
From the data provided in the table below, calculate the acceleration of gravity for each mass:

CALCULATE THE TIME FOR THE MASS TO TRAVEL ONE METER.
Procedure from Lab Worksheet (just FYI).
1. Set up an Atwood machine. Make mass one as a constant of 1 kilogram.
2. Start mass two with 1.05 kg, and make y = 1 meter.
3. Measure the time t for mass two to fall a distance of one meter.
4. Repeat the same measurement for two more times.
5. Now change mass two to 1.06 kg, and repeat the above procedure.
6. Then change mass two to 1.07 kg, 1.08 kg, 1.09 kg, and 1.10 kg to repeat the above procedure.
7. Use the data provided in the following table.
From the data provided in the table below, calculate the average time for the mass to travel one meter:
(Use the unit format shown or it will be scored wrong!)
Using the data provided, calculate the Average Time for each of the trials.
an gn 1 0.214 m/s^2 8.77 m/s^2 2 3 4 5 6 2x1m -0.214% - C1 (3.06s)2Explanation / Answer
from the givne data
m1 = 1 kg
hence in the atwood machine
distance d = 1 m
t is from the data
hence
d = 0.5at^2
a = 2d/t^2
but, a = (m2 - m1)g/(m2 + m1)
hence
g = (m2 + m1)2d/(m2 - m1)t^2
g = 2(1 + m2)d/(m2 - 1)t^2
hence from the data
following is the completed table
