a) A simple harmonic motion is represented by x(t ) = a cos ωt

Obtain expressions for velocity and acceleration of the oscillator. Also, plot the time

variation of displacement, velocity and acceleration of the oscillator.
The time period of a simple pendulum, called ‘seconds pendulum’, is 2 s. Calculate the length, angular frequency and frequency of the pendulum. What is the difference

between a simple pendulum and a compound pendulum?
