Two blocks can collide in a one-dimensional collision. The block on the left has a mass of 0.50 kg and is initially moving to the right at 2.4 m/s toward a second block of mass 0.50 kg that is initially at rest. When the blocks collide, a cocked spring releases 1.2 J of energy into the system. (For velocities, use + to mean to the right, - to mean to the left.) What is the velocity of the first block after the collision? What is the velocity of the second block after the collision? Remember that the blocks cannot pass through each other!
