A car is traveling around a horizontal circular track with radius r = 150 m at a constant speed v = 28 m/s as shown. The angle ?A = 19° above the x axis, and the angle ?B = 55° 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
