Mass1 has velocity1 = 10 m/s heading toward Mass2 of velocity2 = 5 m/s in the same direction. Mass1 collides with Mass2 in an elastic collision. What are their final velocities?
Require solving the conservation of mass AND the conservation of Kinetic Energy together.
The Attempt at a Solution
I got the answer in the back of the book, but it sure ought to be simpler to do. That's my question. Is there a simpler way?
