If the velocity of a spring mass system which starts from zero is given by 5 sin(3t) then its amplitude of displacement and accelerations are

$\begin{array}{1 1}(a)\;5\; \& \; 3 \\(b)\;1.67\; \& \;15 \\( c)\; 15\; \& \; 1.67 \\(d)\; 15 \; \& \;3 \end{array}$

Can you answer this question?

Displacement $=\large\frac{5}{3}$$(1- \cos 3t)$ and acceleration $= 15 \cos 3t $
Hence b is the correct answer.
