A motorist is about to enter the exit ramp of a highway. When it is 50m before reaching A (along the straight path), the motorist travels at 80km/h, decreasing at the rate of 0.5m/s2until it reaches B. After it reaches B, it travels at a constant speed. Determine the magnitude of the acceleration: just after A just before B just after B
