Answer 1

hey mate I'll Leave Calculation part to you as, I can not even remember those formulas (Although I can derieve them , but I don't have much time )

We know that highest point can be calculated

Let it be ω

this turns out to be the radius of the semicircle formed by the trajectory of the projectile as it will form an arc of radius $\omega$ and we know that $\theta = \frac{arc}{radius}$

so you can calculate total distance travelled by the projectile from point of projection and maximum height ω

total time taken cal also be calculated through the formula of time taken for flight

as total time T is given  by

T= $t_{time of ascent(upto maximum height)}+t_{time of descent (after maximum height)}\\t_{ascent}=t_{descent}$

hence to get average velocity you can just divide these 2 to get your answer

Sorry I 'm in hurry so can't do calculation part for you

let me know if you didn't get the answer by commenting over this answer
