    Where Do Balls Collide When Dropped and Thrown Up Simultaneously?

    Homework Statement A ball A is dropped from the top of a building of height h and simultaneously a ball B is thrown upwards and both balls collide. After the collision the ball A has the double the velocity of ball B Determine the fraction of the building where the balls collide...
