For a uniformly accelerated motion,
v² = v² + 2a (x − xo)
In above equation,
v - End velocity
vo - Start velocity
a - Acceleration
x - End position
co - Start position
Calculation:
Convert,
v = 100 km/h = 27.78 m/s
Find the total distance from point A to C,
dac = (150 m) + 100 m = 335.62 m
Find the tangential component of the acceleration,
From point A to C,
Chapter 11.5, Problem 11.140P
v = v + 2a (dac)
(27.78 m/s)² = 0+2a+ (335.62 m)
at = 1.1497 m/s²

Chapter 11.5, Problem 11.140P
A motorist starts from rest at point A on a circular entrance ramp when t = 0, increases the speed of her automobile
at a constant rate, and enters the highway at point B. Knowing that her speed continues to increase at the same rate
until it reaches 100 km/h at point C, determine (a) the speed at point B, (b) the magnitude of the total acceleration
when t = 20 s.
