Work Energy And Power Question 158
Question: In the above question, if another body is at rest, then velocity of the compound body after collision is
Options:
A) v/2
B) 2v
C) v
D) Zero
Show Answer
Answer:
Correct Answer: A
Solution:
If initially second body is at rest then Initial momentum = $ mv $
Final momentum = $ 2mV$
By conservation of momentum $ 2mV=mv $
therefore $ V=\frac{v}{2} $
