average velocity = total displacement / total time
H is the maximum height and R is the horizontal range of projectile ....
at highest point, projectile is H m above in verticle and R/2 m far in horizontal direction from the point of projection..
displacement = sqrt{ H^2 + (R/2)^2} ={u^2sin@ sqrt(1+3cos^2@) } /g
time taken by projectile to reach to maximum height is t = T/2 =usin@/g
Vavg = usqrt( 1+3cos^2@)
