maximum acceleration if i) springs are connected in series ii) springs are
connected in parallel.

A body is moving with simple harmonic motion and has amplitude of 4.5 m and
period of complete oscillation of 3.5s. Find the time required by the body in
passing between two points which are at a distance of 3.5 m and 1.5 m from the
centre and are on the same side.

In a crank and connecting rod mechanism, the crank and connecting rod are
2.5m and 11.25 m respectively. The crank rotates at 420 rpm. Determine the

velocity of the piston when the crank is at 40° with inner dead centre.
