The car is traveling at a speed of 65 mi/hr as it approaches point A. Beginning at A, the car decelerates at a constant 7.8 ft/sec2 until it gets to point B, after which its constant rate of decrease of speed is 3.0 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. 153' с B B 222' Answers: (a) Just before B, a = FE ft/sec2 (b) Just after B, a = i ft/sec2 (c) At C a = i i ft/sec2
