Question

part V please still not finished

making sure to label variables and constants described above (4 pts). ii. Approximating to three significant digits if necessary, what is the angular frequency of this oscillator on a string? ii. Approximating to three significant digits if necessary, how many cycles per second should we expect of this pendulum? iv. What is the particle's approximate SPEED at t = T/4 seconds? (for which T stands for 'Period' of this pendulum). If your F-B-D (i, above) is correct, you should find it reasonable to believe that: mgsind = ma V. Given this, show how angular frequency depends on both the length of the string and the free-fall acceleration constant due to gravity Note 0 = and lim(sin) = 0 Page 5 of 8

Answer 1

$\omega = \sqrt{\frac{g} {l}}$

Thus frequency is directly proportional to square root of acceleration due to gravity and inversely proportional to square root of length
