11. Momentum & Impulse Completely Inelastic Collisions
22PRACTICE PROBLEM
Consider a collision between two cars, car 1 and car 2, of equal mass (2m), in which car 1 is initially moving with velocity (v) and car 2 is initially stationary at a red traffic light. The collision is partially elastic, where 2/5 of the mechanical energy is dissipated as heat and sound. Find the final velocities of the cars after the collision.
