A particle is projected from the ground with an initial speed of \( v \) at an angle \( \theta \) with horizontal. The average velocity
\( \mathrm{P} \) of the particle between its point of projection and highest

W. point of trajectory is
(1) \( \frac{v}{2} \sqrt{1+2 \cos ^{2} \theta} \)
(2) \( \frac{v}{2} \sqrt{1+2 \cos ^{2} \theta} \)
(3) \( \frac{v}{2} \sqrt{1+3 \cos ^{2} \theta} \)
(4) \( v \cos \theta \)
