Two paper screens A and B are separated by 150 m. A bullet pierces A and then B. The hole in B is 15 cm below the hole on screen A. If the bullet is travelling horizontally at the time of hitting A, then the velocity of the bullet at A is : (Take g = 10 ms-2 )
detailed solution
Correct option is D
Range = 150 = ut andh=15100=12gt2or t2=2100×15g=301000or t=310∴u=150t=150×103=5003ms−1Talk to our academic expert!
