## Homework Statement

Object A has V

_{A}=20m/s going downwards, Object B has V

_{B}=20m/s going upwards. Only gravity is given and they are traveling along a straight line vertically. What is the Δt when they meet and what Δd for object B.

## Homework Equations

5 Kinematic equations + v=Δd/Δt,a=Δv/Δt

## The Attempt at a Solution

I've tried numerous ways to approach this problem, I've concluded that they will meet each other when both times are equal to each other but I don't know how to resolve that given the equations I have. I've tried substituting equations, subtracting, using the quadratic formula to no avail. I'm looking at some advice at how I can understand this problem to improve my grasp of physics, I'm not looking for the answer. I've worked at this for about 4 hours and nothing has come from it, any hits/suggestions would be appreciated.
