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.

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. Given that the part of the bat handle held by the cricketer has a mass of 0.48 kg, calculate the maximum force produced on his hands.

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. The oscillations are damped and die away after about five complete cycles. Sketch a displacement- time graph to show the oscillations.

Seismometers are used to detect and measure the shock waves that travel through the Earth due to earthquakes.

This diagram shows the structure of a simple seismometer. The shock wave will cause the mass to vibrate, causing a trace to be drawn on the paper scroll.

Question Image

The frequency of a typical shock wave is between 30 and 40 Hz. Explain why the natural frequency of the spring- mass system in the seismometer should be very much less than this range of frequencies. This graph shows the acceleration of the mass against its displacement when the seismometer is recording an earthquake.
