A car starts from rest on a curve with a radius of 150 m and accelerates at 1.50 m/s^2. How many revolutions will the car have gone through when the magnitude of its total acceleration is 3.20 m/s^2 ?

total acceleration= sqrt(1.5^2+(v^2/r)^2)
solve for v^2/r
solve for angular displacement, divide by 2PI to get revolutions
