## Homework Statement

here is the link to the problem itself. http://www.modelingphysics.org/consta/challenge.pdf

I have actually done number 1, i can't can't seem to figure out how exactly to piece together 2. I have to come up with a algebraic equation to show exactly when the carts will collide.

Given is:

Cart A: Starts at a position of 0, velocity of zero, and an unknown a acceleration

Cart B: Starts at unknown position, velocity of zero, and unknown acceleration.

## Homework Equations

Exact problem is in link. As far as equations go it uses the kinematic equations

## The Attempt at a Solution

My physics teachers told us to put the variables in a list then plug them into a kinematic equation to solve for a unknown value then.

Cart A:

X=0

V1=0

A=?

Vf=?

t=?

Cart B:

X=?

v1=0

Vf=?

t=?

A=?

_______________________________________________________________________________

A= Acceleration

T= Time

V1= initial velocity

X= Position

VF= Final velocity

Im only confused as this involves puting them into a equation that has them colliding and that is where I am stuck.

I would gladly appreciate the help. Thanks
