The point from where a ball is projected is taken as
\( \mathrm{P} \) the origin of the coordinate axis. The \( \mathrm{x} \) and \( \mathrm{y} \)

W components of its displacement are given by \( x=6 t \) and \( y=8 t-5 t^{2} \). What is the velocity of projection?
(1) \( 6 \mathrm{~ms}^{-1} \)
(2) \( 8 \mathrm{~ms}^{-1} \)
(3) \( 10 \mathrm{~ms}^{-1} \)
(4) \( 14 \mathrm{~ms}^{-1} \)
