Questions
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 )
detailed solution
Correct option is B
Let bullets collide at time tx1+x2=100m25t + 25t = 100t = 2 sy=12gt2=12×10×22 = 20h = 200 – 20 = 180 mHence bullets will collide after 2 s at height 180 m above the ground.Talk to our academic expert!
