Suppose you pull a simple pendulum to one side by an angle of 5∘, let go, and measure the period of oscillation that ensues. then you stop the oscillation, pull the pendulum to an angle of 10∘, and let go. the resulting oscillation will have a period about the period of the first oscillation.

The slotted link is pinned at o, and as a result of rotation it drives the peg p along the horizontal guide. compute the magnitude of the velocity and acceleration of p along the horizontal guide. compute the magnitudes of the velocity and acceleration of p as a function of θ if θ=(3t) rad, where t is measured in seconds.
