(a) Define the term 'oscillation' and give one example of an oscillating system
(b) Show that the total energy of a particle moving with simple harmonic motion is a constant and
derive an expression for this energy.
(c) A car with a mass of 1 300 kg is constructed so that its frame
is supported by four springs. Each spring has a force constant
of 20 000 N/m. If two people riding in the car have a combined mass of 160 kg, find
the frequency of vibration of the car after it is driven over a pothole in the road.
