For the damped oscillator shown in previous Figure, the mass m of the block is 400 g, `k=45 Nm^(-1)` and the damping constant b is `80 g s^(-1)`. Calculate . (a) The period of osciallation , (b) Time taken for its amplitude of vibrations to drop to half of its initial value and (c ) The time taken for its mechanical energy to drop to half its initial value.
