A car is traveling around a horizontal circular track with radius r = 250 m at a constant speed v = 25 m/s as shown. The angle θA = 19° above the x axis, and the angle θB = 58° below the x axis.

I got the magnitude of car's acceleration but can't find the answer for these.
1) What is the x and y component of the car's acceleration when it is at point A
2) What is the x and y component of the car's acceleration when it is at point B

Thank you

The centripedal accelaration is a vector, having a certain magnitude and a direction toward the center of the circle. It's magnitide is


|\vec a| = w^2 R = \frac {v^2} R


The x component is that magnitude times the \cos \theta . And the y component is the magnitude times \sin \theta
