A particle of mass m moving with velocity `vecV` makes a head on elastic collision with another particle of same mass initially at rest. The velocity of the first particle after the collision will be

A

`-2vecv`

B

`vecv`

C

`-vecv`

D

zero

Text Solution

Verified by Experts

The correct Answer is:
D
When the bullet and the block of equal masses, collide, they exchange their velocities i.e., 100% energy,is transferred.
`[ K.E. = (1)/(2) mv^(2) ]`
Thus, transfer of energy is maximum , when `M = M'`.
