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.
