Problem A car starts from rest on a circular track, and accelerates with a constant angular acceleration of 0.1 rad/s. The track has a radius of 100 m. How long does it take to go around the track once? At this time, what is the magnitude of its Tangential acceleration? Radial acceleration? Sketch the track, showing the direction of the total acceleration vector at this time.
