A body is moving with a velocity v , breaks up into two equal parts. One of the part retraces back with velocity v . Then the velocity of the other part is

A

v in forward direction

B

3v in forward direction

C

v in backward direction

D

3v in backward direction

Text Solution

Verified by Experts

The correct Answer is:
B
`mv= (m/2) (-v) +m/2 (v_2)`
`implies (3v)/2=v/2 implies v_2 = 3v` Forward.
