Question:
Car \(A\) is accelerating in the direction of its motion at the rate of \(3 \mathrm{ft} / \mathrm{sec}^{2}\). Car \(B\) is rounding a curve of \(440-\mathrm{ft}\) radius at a constant speed of \(30 \mathrm{mi} / \mathrm{hr}\). Determine the velocity and acceleration which car \(B\) appears to have to an observer in car \(A\) if car \(A\) has reached a speed of \(45 \mathrm{mi} / \mathrm{hr}\) for the positions represented.
