(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

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.

2. Relevant equations

v = v_{0}+at

x = x_{0}+ v_{0}t + (1/2)at^{2}

v^{2}= v^{2}_{0}+2a(x- x_{0})

3. 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
