Question The car is traveling at a speed of 60 mi/hr as it approaches point A. Beginning at A, the car decelerates at a constant 7ft/sec^2 until it gets to point B, after which its constant rate of decrease of speed is 3 ft/sec^2 as it rounds the interchange ramp. Determine the magnitue of the total car acceleration a) just before it gets to B, b) just after it passes B, and c) at point C.
