Acar is traveling around a horizontal circular track with radius r = 220 m as shown. it takes the car t = 61 s to go around the track once. the angle θa = 23° above the x axis, and the angle θb = 57° below the x axis.
1) what is the magnitude of the car’s acceleration?
2) what is the x component of the car’s velocity when it is at point a
3) what is the y component of the car’s velocity 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
