The point from where a ball is projected is taken as the origin of the coordinate axes. The \( \mathrm{x} \) and \( \mathrm{y} \) components of its displacement are given by \( x=6 t \) and \( y=8 t-5 t^{2} \).
\( \mathrm{P} \) What is the velocity of projection ?]

W)
(1) \( 6 \mathrm{~m} \mathrm{~s}^{-1} \)
(2) \( 8 \mathrm{~m} \mathrm{~s}^{-1} \)
(3) \( 10 \mathrm{~m} \mathrm{~s}^{-1} \)
(4) \( 14 \mathrm{~m} \mathrm{~s}^{-1} \)
