Two bullets are fired horizontally and simultaneously towards each other from roof tops of two buildings 100 m apart and of same height of 200 m, with the same velocity of 25 m/s. When and where will the two bullets collide? (g = 10 m/s 2 )
Text Solution
Verified by ExpertsThe correct answer is:
A
Now x 1 = 25t ; x 2 = 25t
x 1 + x 2 = 100 = 50t
so t = 2 sec
and vertical downward displacement
h = 
gt 2 = 
×10×4 = 20 meter
so height from ground ⇒ 200 – 20 = 180 meter
