A body with a mass of 0.5 kg hangs on a 1 m-long rope attached to the ceiling. Draw a sketch with all the relevant quantities.
Calculate the oscillation period of this pendulum.
How does the oscillation period of the pendulum change and by what percentage if the length is cut into half?
How would the oscillation period of the pendulum change if the body is doubled?
What are the maximum speed and acceleration of the pendulum with half of the length if the body is swung with an amplitude of 5 cm?
At what frequency should we force this half-length pendulum to oscillate in order for resonance to occur?
and the maximum acceleration is 
.
