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 8 ft/s? until it gets to
point B, after which its constant rate of decrease of speed is 3 ft/s² 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. Use 1 mile = 5280 ft.
