1. The problem statement, all variables and given/known data A 0.147 glider is moving to the right on a frictionless, horizontal air track with a speed of 0.870 . It has a head-on collision with a 0.292 glider that is moving to the left with a speed of 2.20 . Suppose the collision is elastic. What is the magnitude of the final velocity of both carts after the collision? 2. Relevant equations M1U1+M2U2=M1V1+M2V2 3. The attempt at a solution I can setup the equation and determine the direction both carts are traveling after the collision but with 2 unknowns for the final speeds I dont know how to find the exact speed each is traveling after the collision.
