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