## Homework Statement

2 objects A and B.

A has a 4000 m. head start on x-axis heading to the right

V

_{a}= 50 m/s;

V

_{b}= 55 m/s

a

_{a}= 0.5 m/s

^{2}

a

_{b}= 1.0 m/s

_{2}

need to know t in s when x

_{a}= x

_{b}

## Homework Equations

r = r

_{0}+vt-a(t

^{2}/2)

## The Attempt at a Solution

I set each up for x

_{a,b}in said equation and set them equal to each other.

I plugged and chugged to a quadratic equation and ended up with a horrible answer of 140.04 seconds which makes no sense and then the other answer was negative
