NEET Physics Question - Kinematics - Projectile from Height

Horizontal motion: Bullets move towards each other with relative velocity 50 50 m/s. Time to meet: t = 100 50 = 2 s t = \frac{100}{50} = 2 \text{ s}
Vertical motion: Free fall equation: H = 200 − 5 t 2 = 200 − 5 ( 2 ) 2 = 180 m H = 200 - 5t^2 = 200 - 5(2)^2 = 180 \text{ m}

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/s²)

They will not collide

After 2 s at a height of 180 m
