P
If a man has a velocity varying with time given as \( v= \)
W \( 3 t^{2}, v \) is in \( \mathrm{m} / \mathrm{s} \) and \( t \) in sec then:
Regarding the velocity of man choose the correct \( \operatorname{option}(\mathrm{s}) \) :
(1) Velocity of man after \( t=3 \mathrm{sec} \) is \( 27 \mathrm{~m} / \mathrm{s} \)
(2) Velocity of man after \( t=3 \mathrm{sec} \) is \( 9 \mathrm{~m} / \mathrm{s} \)
(3) Average velocity of man during \( t=0 \) to \( t=3 \) \( \sec \) is \( 9 \mathrm{~m} / \mathrm{s} \)
(4) Average velocity of man during \( t=0 \) to \( t=3 \) \( \sec \) is \( 27 \mathrm{~m} / \mathrm{s} \)
