The car is traveling at a speed of 68 mi/hr as it approaches point A. Beginning at A, the car decelerates at a constant 8.0 ft/sec² until it gets to point B, after which its constant rate of decrease of speed is 2.3 ft/sec² as it rounds the interchange ramp. Determine the magnitude of the total car acceleration (a) just before it gets to B. (b) just after it passes B, and (c) at point C. Answers: (a) Just before B, a= (b) Just after B, 319' (c) At C, a = a= M. i 201¹ C ft/sec² ft/sec² ft/sec² 2
