Two blocks can collide in a one-dimensional collision. The block on the left hass a mass of 0.40 kg and is initially moving to the right at 2.4 m/s toward a second block of mass 0.60 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.)
(a) What is the velocity of the first block after the collision? _______ m/s
(b) What is the velocity of the second block after the collision? _______ m/s
Remember that the blocks cannot pass through each other!
