A body of mass 0.20kg attached to a spring executes simple harmonic motion with amplitude 0.10m and time period 0.50s.
(i) Calculate the angular frequency ω of the motion.
(ii) Find the speed of the body when its displacement from the equilibrium position is 0.050m.
(iii) Determine the maximum speed of the body and compare it with the value obtained in part (ii).
