1. The problem statement, all variables and given/known data A 111g ball is tied to a string. It is pulled to an angle of 4.40 Degrees and released to swing as a pendulum. A student with a stopwatch finds that 17 oscillations take 19.0s. How long is the string? 2. Relevant equations T = 2π√(L/g) 3. The attempt at a solution Period T = 19/17 = 1.118s g = 9.8m/s2 1.118/2π = √L/g 0.1779 = √L/g 0.0316 = L/g L = 0.3101cm This is wrong, someone please tell me my mistake.
