A bullet of mass fired with a speed from passes through a block of wood whose centre is kept at a distance of from the origin as shown in figure. The retarding force on the bullet within the wooden block is . The minimum length of the block (upto one decimal digit) required to completely stop the bullet is (Assume )
- A
- B
- C
- D
Answer & Solution
Correct Answer
(D)
Step-by-step Solution
Detailed explanation
Given Mass of bullet m=1 kg Velocity of bullet v=2 m s-1 The restoring force on the bullet within the block is F=-0.5x Applying work energy theorem, W=∆KE ⇒ ∫F dx=-12mu2…
