Suppose now that the air carts below are both moving to the right initially. The cart to the left has a mass m1 and an initial speed v0; the cart to the right has an initial speed v0/2. If the center of mass of this system moves to the right with a speed 6/7 multiplied by v0, what is the mass of the cart on the right?
The answer is to be expressed in terms of mass 1.
I got .45 but that isn't correct.

m1*vo+m2(vo/2)=(m1+m2)6vo/7
solve for m2
