The acceleration time graph
of a particle is shown in the
figure-1.140. What is the velocity
of particle at \( t=8 \mathrm{~s} \), if initial velocity
of particle is \( 3 \mathrm{~m} / \mathrm{s} \) ? (Assume motion
is \( 1 \mathrm{dimension} \) :
\( \begin{array}{ll}\text { (A) } 4 \mathrm{~m} / \mathrm{s} & \text { (B) } 5 \mathrm{~m} / \mathrm{s} \\ \text { (C) } 6 \mathrm{~m} / \mathrm{s} & \text { (D) } 7 \mathrm{~m} / \mathrm{s}\end{array} \)
