Two paper screens A and B are separated by 150 m. A bullet pierces A and B. The hole in B is 15 cm below the hole in A. If the bullet is travelling horizontally at the time of hitting A, then the velocity of the bullet at A is: (g: 10 ).
detailed solution
Correct option is D
Range = 150 = ut and h = 15100 = 12×gt2or t2 = 2×15100×g = 301000∴ t = 310∴ u = 150t = 150×103 = 5003 ms-1Talk to our academic expert!
