a particle is projected upward from ground with a speed u at an angle alpha with the horizontal . At the same time, another particle is droped from a height h. If they could collide at a horizontal distance ss from the point if projection, h is

Answer 1

Answer:

please mark me brainlist

Explanation:

Time for the 1st particle to reach the ground: t=

g

2h

The 2nd particle travels a distance d in time t at constant horizontal speed u.

∴d=ut

d=u

g

2h

⇒d

2

=

g

2u

2

h
