The velocity of the centre of mass equals the total momentum divided by:
ATotal time
BTotal force
CTotal charge
DTotal mass
Answer & Solution
Correct answer: D. Total mass
1. Momentum of the system is written as P.
2. It is shared over the mass M of the whole system.
3. So the centre of mass velocity is P over M.
