my book says " the total momentum is zero in the centre of mass reference frame.This should not surprise you"
but ITS NOT INTUITIVE FOR ME.
I am considering a completely elastic collision.
1. I know the v_cm is const because there are no ext forces on the system of the two masses undergoing 1D elastic collision
2. I know the momentum and energy is conserved.
3. I know how to find out the v_cm and relative velocities.
Help me get a feel for it
