Relative Motion on a Curve#

../../../../../_images/L11Q4.png

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 47km/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?

Answer Section#

Part 2#

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