"a car is travelling 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? "
