A train is moving towards East with a speed \( 20 \mathrm{~m} / \mathrm{s} \). A person is running on the roof of the train with a speed
\( \mathrm{P} \) \( 3 \mathrm{~m} / \mathrm{s} \) against the motion of train. Velocity of the

W person as seen by an observer on ground will be :
(1) \( 23 \mathrm{~m} / \mathrm{s} \) towards East
(2) \( 17 \mathrm{~m} / \mathrm{s} \) towards East
(3) \( 23 \mathrm{~m} / \mathrm{s} \) towards West
(4) \( 17 \mathrm{~m} / \mathrm{s} \) towards West
