A strong magnet of mass 0.04 kg falls 0.78 m under the action of gravity from position
The magnet takes 0.5 seconds to pass through the cylinder. The displacement-time graph of the magnet is shown.
Analyse the motion of the magnet by applying the law of conservation of energy.
Your analysis should refer to gravity and the copper cylinder, and include both qualitative and quantitative information. (9 marks)
