Two paper screens A and B are separated by . A bullet pierces A and then B. The hole in B is below the hole in A. If the bullet is traveling horizontally at the time of hitting A, then the velocity of the bullet at A is:
- A
- B
- C
- D
Answer & Solution
Correct Answer
(D)
Step-by-step Solution
Detailed explanation
The bullet exhibits horizontal projectile motion. Displacement of bullet in vertical direction,y=15 cm=0.15 m Displacement of bullet in horizontal direction,x=150 m The equation of trajectory, y=gx22u2 ⇒0.15=10×15022u2 ⇒2u2=10×15020.15…
