1. The problem statement, all variables and given/known data Object A has VA =20m/s going downwards, Object B has VB=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. 2. Relevant equations 5 Kinematic equations + v=Δd/Δt,a=Δv/Δt 3. 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 dont 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.
