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.
