Question
Table 1. Rotational Data Radius (m) Time per 15 revolutions (s) Period (s) Expected Value Percent Error (%) 0.25 6.72s 0.448s 2.01 77.7% 0.40 7.99s
Table 1. Rotational Data
Radius (m) | Time per 15 revolutions (s) | Period (s) | Expected Value | Percent Error (%) |
0.25 | 6.72s | 0.448s | 2.01 | 77.7% |
0.40 | 7.99s | 0.533 | 2.54 | 79.0% |
0.15 | 5.87s | 0.391 | 1.56 | 74.9% |
I need help finding my expected value. I do not think I answered these correctly based on my answer in pre lab question 1.
Pre lab question 1: In this lab, you will be rotating a mass on one side of a string that is balanced by a second mass on the other end of the string (Figure 5). Apply Newton's Second Law of Motion to mass 1, m1, and mass 2, m2, to solve for the period of mass 1.
