Question

1. The hanging mass from the apparatus was removed by unhooking the spring and the string
and the mass was determined to be 1200 grams. The mass was reattached to the string from
the top cross arm.
2. The diameter of the center pole was measured using the vernier caliper and it found to be
1.279 cm

Using information above, and data in table calculate following:

  1. Calculate the angular velocity (ω).
  2. Calculate the linear speed of the mass (Vt).
  3. Calculate Percent error between the Spring Force and Centripetal Force.
  4. Calculate Fc based on the information shown
