# A car is traveling around a horizontal circular track with radius r = 230

A car is traveling around a horizontal circular track with radius r = 230 m at a constant speed v = 17 m/s as shown. The angle θA = 39° above the x axis, and the angle θB = 56° 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

6)As the car passes point B, the y component of its acceleration is(choose one):

increasing

constant

decreasing
