Here, velocity of projection, u = 28 m/s. Angle of projection,  = 30০. 

We have, maximum height attained by a projectile, 

So, the maximum height attained by the ball is 20 m.

It sould be,
      


So, the maximum height attained by the cricket ball will be 10 

Answer 2

use
$( {u}^{2} ({ \sin( \alpha ) })^{2}) \div 2g$
