The ceiling of a

Answer :

Given: u = 56 ms–1;


At the highest point, the vertical component of velocity is zero and is constant throughout the projectile since.


Now, using equations of motion:



So, now for vertical motion at max height:


,


a = –g, ,


s =




Now, from above, Ɵ should be such that,








So, here limiting case is


So, for this limiting case, horizontal range is:
