Find the average velocilty of a projectile between the instants it crosses half the maximum height. It is projected with speed u ast angle `theta` with the horizontal.

Find the average velocity of a projectile between the instants it crosses half the maximum height. It is projected with speed u at angle theta with the horizontal.

A stone projected with a velocity u at an angle q with the horizontal reaches maximum heights H_(1) . When it is projected with velocity u at an angle (pi/2-theta) with the horizontal, it reaches maximum height H_(2) . The relations between the horizontal range R of the projectile, H_(1) and H_(2) , is
