What is the magnitude of the car’s acceleration?

A car is traveling around a horizontal circular track with radius r = 150 m at a constant speed v = 20 m/s as shown. The angle θA = 30° above the x axis, and the angle θB = 54° below the x axis.
1) What is the magnitude of the car’s acceleration?
2) What is the x component of the car’s acceleration when it is at point A?
3) What is the y component of the car’s acceleration when it is at point A?
4) What is the x component of the car’s acceleration when it is at point B?
5) What is the y component of the car’s acceleration when it is at point B?
6) As the car passes point B, the y component of its acceleration is:?
increasing
constant
decreasing
