    Find the acceleration of a race car traveling up a curve

    Homework Statement A 500 kg race car starts at rest on a curve with a radius of 50 m. If it goes 20 degrees in 4 seconds with a constant angular acceleration, what is its total acceleration at the end of this time? m=500kg r = 50 m angle = pi/9 radians time = 4...
