I'm not sure how this can be solved if their is only two velocities?
Two balls are approaching each other head-on. Their velocities are +9.95 and -11.4 m/s.
(a) Determine the velocity of the center of mass of the two balls if they have the same mass.
(b) Determine the velocity of the center of mass of the two balls if the mass of one ball (v = 9.95 m/s) is twice the mass of the other ball (v = -11.4 m/s).
it took me hours to find the equation to be 1/2(x1 + x2) in a textbook. where x1 = v1 and x2 = v2
i didn't use the masses at all. just the velocities only.
i wish you could've pointed me in that direction!
so for the first one, -.725 m/s and the second one. the mass should not make a difference. but i could not reach an answer.
Now plug the numbers in.
For the second problem we have , so
You finish it.
