A body of mass m moving with a constant velocity v hits another body of the same mass moving with the same velocity v but in the opposite direction and sticks to it. The velocity of the compound body after collision is
Text Solution
Verified by ExpertsThe correct answer is:
C
Initial momentum of the system = $m\mathbf{v} - m\mathbf{v} \equiv 0$
As body sticks together ∴ ∴ final momentum = $2 \mathrm{mV}$
By conservation of momentum $2mV = 0$ ∴ ∴ V = 0
