Exercise: VibrationEquipment:
Place the cart on the air track and attach springs so that it can vibrate. 1. Test whether the period of vibration depends on amplitude. Try at least two moderate amplitudes, for which the springs do not go slack, and at least one amplitude that is large enough so that they do go slack. 2. Try a cart with a different mass. Does the period change by the expected factor, based on the equation
3. Use a spring scale to pull the cart away from equilibrium, and make a graph of force versus position. Is it linear? If so, what is its slope? 4. Test the equation
numerically.
