0A particle starts from the origin with a velocity of \( 10 \mathrm{~m} \mathrm{~s}^{-1} \) and moves with a constant acceleration till the velocity
\( \mathrm{P} \) increases to \( 50 \mathrm{~m} \mathrm{~s}^{-1} \). At that instant, the acceleration is
W suddenly reversed. What will be the velocity of the particle, when it returns to the starting point?
(1) Zero
(2) \( 10 \mathrm{~m} \mathrm{~s}^{-1} \)
(3) \( 50 \mathrm{~ms}^{-1} \)
(4) \( 70 \mathrm{~m} \mathrm{~s}^{-1} \)
