Damped and forced oscillations, resonance — practice question

A body is moving in simple harmonic motion. Figure 3.1 shows how its velocity $v$ varies with displacement $x$.
(a(i))[1]

State the oscillation amplitude $x_0$.

(a(ii))[3]

Calculate the oscillation period $T$.

(a(iii))[1]

On Fig. 3.1, place a P at a point where the body has its maximum potential energy.

(b(i))[2]

State Faraday’s law for electromagnetic induction.

(b(ii))[3]

The switch is now closed. Explain why the magnet’s oscillations are damped.
