# Relative Motion on a Curve#

On a relatively quiet lake, two boats approach each other. Boat A has been speeding in circles, $$r = {{params.r}}m$$, at a constant speed of 38km/hr. When A is as shown, B is $$d = {{params.d}} m$$ from the curve representing A’s path, and is accelerating at a rate of $${{params.a}} m/s^2$$. Assume $$\theta = {{params.theta}}^{\circ}$$.

## Part 1#

What is the acceleration of A as seen by Boat B?

## Part 2#

What is the angle of the acceleration vector of A measured from the west axis?
