Question

A car is traveling around a horizontal circular track with radius r = 190 m at a constant speed v = 15 m/s as shown. The angle ?A = 29° above the x axis, and the angle ?B = 54° 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
a) increasing
b) constant
c) decreasing
