Question Solved1 Answer 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. Constants 1 Periodic Table Suppose that the the initial speed of cart 2 is u. What is the speed of cart 1 right after the collisionit the collision is elastic? Express your answer in terms of u. V AED * * O2 ? XXX104 ViVx Submit Previous Answers Request Answer
