The velocity-time graph of a particle moving along a straight line is shown in figure The rate of acceleration and deceleration is constant and it is equal to \( 5 \mathrm{~m} \mathrm{~s}^{-2} \). If the average velocity during the motion is \( 20 \mathrm{~m} \mathrm{~s}^{-1} \), then
\( P \)
The maximum velocity of the particle is
(1) \( 20 \mathrm{~ms}^{-1} \)
(2) \( 25 \mathrm{~ms}^{-1} \)
(3) \( 30 \mathrm{~ms}^{-1} \)
(4) \( 40 \mathrm{~ms}^{-1} \)
