Two objects are approaching each other on a collision course. each object has a speed of 10 m/s. the mass of object 1 is m1 and the mass of object 2 is m2. after they collide head on, object 2 comes to a complete stop, and object 1 bounces off object 2 and moves away at
5 m/s. what is the mass of object 2 in terms of m1?
