Frequency and Period of SHM

AP Physics 1· difficulty 1/5

A pendulum makes 3030 oscillations in 60 s60~\text{s}. Its period and frequency are

  • A

    1.0 s1.0~\text{s}, 0.5 Hz0.5~\text{Hz}

  • B

    2.0 s2.0~\text{s}, 0.5 Hz0.5~\text{Hz}

  • C

    0.5 s0.5~\text{s}, 2 Hz2~\text{Hz}

  • D

    60 s60~\text{s}, 30 Hz30~\text{Hz}

Explanation

T=60/30=2.0 sT = 60/30 = 2.0~\text{s}. f=1/T=0.5 Hzf = 1/T = 0.5~\text{Hz}.
