Question: Two carts are initially moving to the right on a low-friction track, with cart 1 behind cart 2 . Cart 1 has a speed twice

Two carts are initially moving to the right on a low-friction track, with cart 1 behind cart 2 . Cart 1 has a speed twice that of cart 2 and so moves up and rear-ends cart 2 , which has twice the inertia of cart 1 . What is the speed of each cart right after the collision if the collision is elastic?
