The acceleration of an object is given by \( a(t)=\cos \pi t \)
\( \mathrm{P} \)
\( \mathrm{ms}^{-2} \) and its velocity at time \( t=0 \) is \( \frac{1}{2 \pi} \mathrm{ms}^{-1} \) at origin. Its velocity at \( t=\frac{3}{2} s \) is
(1) \( -\frac{1}{2 \pi} \mathrm{ms}^{-1} \)
(2) \( \frac{3}{2 \pi} \mathrm{ms}^{-1} \)
(3) \( \quad \frac{1}{\pi} \mathrm{ms}^{-1} \).
(4) \( \frac{2}{\pi} \mathrm{ms}^{-1} \)
