The period of oscillation is 3 s, calculate the length of the pendulum.
| June 15, 2021 | education
Pendulum oscillation period T:
T = 2п√ (L / g), where L is the length of the pendulum thread, g is the acceleration of gravity.
Find the length of the pendulum thread:
√L = (T√g) / (2п);
L = (T ^ 2 * g) / 4n ^ 2 = (9 s2 * 10 m / s2) / (4 * 3.14 ^ 2) = 90 m / 39.4384 = 2.282 m.
Answer. The pendulum is 2.282 m long.
