The child moves so the theta is increasing as time passes but I'm not sure how to solve for it.
And the x-component is 8*sin(theta) and y-component is 8*cos(theta)
But now I'm thinking, what if instead of 8*cos(theta) it's actually 8*cos(theta)-2? That way the child moving is subtracted from the moving boat.

Google Translate gives "current dislocation", so maybe current vector? Or current velocity?
