A pendulum has a length of 1m. What is the period of this pendulum? What is the frequency of this pendulum?

You measure the period of a pendulum and get 25s. What is the length of the pendulum?

  • physics -

    he period of a pendulum is independent of its mass:

    T= 2*pi*sqrt(l/g)(is seconds)
    frequency = 1/T

    if you have T 25s and g 9.81 m/s²
    you can find l for T=25s :)
