Question

The car is travelling at a speed of 95 km/h as it approaches point A. Beginning at A, the

car decelerates at a constant 2 m/s^2

until it gets to point B, after which its constant rate of

decrease of speed is 0.9 m/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.
