## Homework Statement

A ball is dropped from the top of a 50.0 rm m-high cliff. At the same time, a carefully aimed stone is thrown straight up from the bottom of the cliff with a speed of 21.0 m/s. The stone and ball collide part way up.

## Homework Equations

v = v

_{0}+at

x = x

_{0}+ v

_{0}t + (1/2)at

^{2}

v

^{2}= v

^{2}

_{0}+2a(x- x

_{0})

## The Attempt at a Solution

Two objects, each with different components of one-dimensional motion. The two objects will share a common impact time because they are put into motion at the same time. I have tried solving for time and setting the equations equal to each other, but this yields no result because when I arrange the quadratic formula it evaluates to y = 0, which doesn't make sense. I don't need explicit help (although I don't mind, I just hate typing this out so I don't expect people trying to help me to), I just need a direction to take this problem.

Thanks
