What have you tried?

I assume that you know the kinematic equations.

$\displaystyle x=x_{0}+v_{0}t+\frac{1}{2}at^{2}$

For each of the particles you are given the initial position $\displaystyle x_{0}$

Their initial velocity $\displaystyle v_{0}$ and their acceleration $\displaystyle a$.

Hint: for simplicity since Z is arbitrary and you are only care about distance from z you might as well put the origin of your coordinate system at z and so $\displaystyle z=0$.

Now write out each of the kinematic equations you will get a system of 2 equations in x and t. - Jul 8th 2010, 08:44 AMAckbeet
What ideas have you gotten so far?
