Question

A 32 N force stretches a vertical massless spring by 0.2 m. (+; above the equilibrium position, −; below the equilibrium
position, U; upwards, D: downwards, g = 10 m/s2)
If the amplitude of the oscillation is 0.1 m and the period is 0.5 s, where is the object and in what direction is it moving 5/24s after it has passed the equilibrium position, moving downward?
(a) −0.05 m U (b) −0.05 m D (c) +0.05 m U (d) −0.05√
3 m D (e) −0.05√3 m U
