Car A is accelerating in the direction of its motion at the rate of 3 [ft/sec²]. Car B is rounding a curve of 440 [ft] radius at a constant speed of 30 [mi/hr]. Determine the velocity (in [ft/sec]) and acceleration (in [ft/sec²]) which car B appears to have to an observer in car A if car A has reached a speed of 45 [mi/hr] for the positions represented. --+-- 30° A 440' B
