Relative Motion on a Curve#

On a relatively quiet lake, two boats approach each other. Boat A has been speeding in circles, $r=params.rm$, at a constant speed of 49km/hr. When A is as shown, B is $d=params.dm$ from the curve representing A’s path, and is accelerating at a rate of $params.am/s^2$. Assume $\theta ={params.theta}^{\circ }$.
