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

Car traveling on circular track. Point A is at positive x,y. Point B is at positive x, negative y.

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
