You ride a bicycle around on a circular track while accelerating. The circle has a radius of 22 m and your cell phone tells you that your total acceleration is 12 m/s2 making an angle 44⁰ from the forward direction of your bike (t̂) into the circle. Find: (a) your radial acceleration, (b) your current speed, and (c) the rate of change of your speed.
