When a cricket ball hits a cricket bat at high speed it can cause a standing wave to form on the bat. In one such example, the handle of the bat moved with a frequency of 60Hz with an amplitude of 2.8mm. The vibrational movement of the bat handle can be modelled on simple harmonic motion. Calculate the maximum acceleration of the bat handle.

This diagram shows a turntable with a rod attached to it a distance From the centre. The turntable is illuminated from the side so that a shadow is cast on a screen.
A simple pendulum is placed behind the turntable and is set oscillating so that it has an amplitude equal to the distance of the rod from the centre of the turntable. The speed of rotation of the turntable is adjusted. When it is rotating at Revolutions per second the shadow of the pendulum and the rod are found to move back and forth across the screen exactly in phase. Explain what is meant by the term in phase.
