Part -1:

1. Calculate the mean value and standard deviation of R.

2. At each spring setting, calculate the values of the angular speed, w, from eq 6-3, for each value of At.

3. At each spring setting, calculate mean values and standard deviations of co.

4. At each spring setting, calculate the centripetal force, mo.)2R, (eq 6-4) using mean values of w and R.

5. F is the force supplied by the spring. Calculate F = (madded + m)g Calculate of by multiplying the mass uncertainty by g.

Part -2:

1. How would 1 min 0.75 s appear on the stopwatch?

2. A centripetal force acts toward the center of the circular motion. Which of the following forces are centripetal?

a) The force the spring exerts on the cylinder.

b) The force the cylinder exerts on the spring.

c) The force the spring exerts on the fixed end.

3. What effect, if any, does the mass of the spring have on the experiment? What would happen if a spring were rotated without any extra mass on its end?
