A bullet fired into a target losses one-third of its velocity after travelling a distance meter into the target. If the bullet comes to rest by travelling a further distance , then the ratio is
- A
- B
- C
- D
Answer & Solution
Correct Answer
(C)
Step-by-step Solution
Detailed explanation
Initial velocity =u. Velocity after covering a distance of x m=2u3. For first part of the motion, we can write v2=u2+2as⇒2u32=u2-2ax⇒2ax=5u29 ...Eq1 For the second part of the motion when bullet comes to rest, we can write…
