A car is traveling around a horizontal circular track with radius r = 270 m at a constant speed v = 17 m/s as shown. The angle θA = 23° above the x axis, and the angle θB = 58° below the x axis.
1. What is the x component of the car’s acceleration when it is at point A?
2.What is the y component of the car’s acceleration when it is at point A?
3.What is the x component of the car’s acceleration when it is at point B?
4. What is the y component of the car’s acceleration when it is at point B?
I found the magnitude of the car's acceleration to be 1.07m/s^2. But all the tangential and radial angles are really confusing me at the moment =(. If anyone could help me or just briefly explain that would be great.
