Learning Goal: To understand how to find the velocities of objects after a collision. There are two main types of collisions that you will study: perfectly elastic collisions and perfectly inelastic collisions. When two objects collide elastically, both total kinetic energy and total momentum are conserved. These two conservation laws allow the final motion of the two objects to be determined. When two objects collide inelastically, total momentum is conserved, but the total kinetic energy is not conserved. After a perfectly inelastic collision, the two objects are stuck together, and thus travel with the same final velocity. This fact, together with conservation of momentum, allows the final motion of the two objects to be calculated. In reality, there is a range of collision types, with elastic and perfectly inelastic at the extreme ends. These extreme cases allow for a more straightforward analysis than the in-between cases. The video at the end of the problem will give you a chance to explore the "in-between" collisions.Part A If the collision is perfectly elastic, what are the final velocities v1 and v2 of objects 1 and 2?
