C5B.8 Consider two carts with nearly frictionless wheels, one with a mass m, and the other with a mass of m2 = 2m1. The lighter one initially moves on a level surface at a speed of Ivo | in the + x direction toward the other. After they collide, we observe the massive cart to move at a speed of | 2 | = To | in the +x direction. What is the velocity , (magnitude and direction) of the lighter cart after the collision? Express the magnitude as a fraction of |do . (Hints: You do not need to describe your model. Let's stipulate that the total momentum of the two-cart system is conserved because the system is functionally isolated. You may also assume that the problem is entirely one-dimensional, though you still need to remember that momentum is a vector.)
