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 km/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?
