1.	A particle is projected from the ground with an initial speed of v at an angle of projection theta. The average velocity of the particle between its time of projection and time it reaches highest point of trajectory is
Answer» `v/2 SQRT(1+ 2 COS^2 theta)` `v/2 sqrt(1+2 sin^2 theta)` `v/2 sqrt(1+ 3cos^2 theta)` `v cos theta ` ANSWER :C
