A particle executes linear SHM with frequency $0.25 \mathrm{~Hz}$ about the point $x=0$. At $t=0$, it has displacement $x=0.37 \mathrm{~cm}$ and zero velocity. For the motion, determine the (a) period, (b) angular frequency, (c) amplitude, (d) displacement $x(t),(\mathrm{e})$ velocity $v(t)$,
(f) maximum speed, (g) magnitude of the maximum acceleration,
(h) displacement at $t=3.0 \mathrm{~s}$, and
(i) speed at $t=3.0 \mathrm{~s}$
