Displacement, Amplitude, Period and Frequency
 

Displacement, Amplitude, Period and Frequency problem 29


We hang a weight of 2 kg on a 20 cm long rope and get a simple pendulum. We force the pendulum to oscillate with frequencies:






  • In which case will the amplitudes be the largest?

  • What should be the length of the pendulum so that the frequency is 0.35 Hz and the pendulum will be in resonance?

  • How many kilogram weights must we hang on the pendulum so that the oscillation frequency is 0.1 Hz?
