The pendulum of a grandfather clock swings from one side to the other in $1.00 \mathrm{s}$. The amplitude of the oscillation is $12 \mathrm{cm}$. Calculate the speed of the bob when its displacement is $6 cm.$

A trolley of mass $m$ Is fixed to the end of a spring. The spring can be compressed and extended. The spring has a force constant $k$. The other end of the spring is attached to a vertical wall. The trolley lies on a smooth horizontal table. The trolley oscillates when it is displaced from its equilibrium position. Show that the motion of the oscillating trolley is S.H.M.

A trolley of mass $m$ Is fixed to the end of a spring. The spring can be compressed and extended. The spring has a force constant $k$. The other end of the spring is attached to a vertical wall. The trolley lies on a smooth horizontal table. The trolley oscillates when it is displaced from its equilibrium position. Show that the period $T$ Of the trolley is given by the equation: $T=2\pi \sqrt{\frac{m}{k}}$.

To start a pendulum swinging, you pull it slightly to one side.

What kind of energy does this transfer to the mass?

To start a pendulum swinging, you pull it slightly to one side. Describe the energy changes that occur when the mass is released.
