SUMMARY
A car travels around a track at a speed of 5 revolutions per second, starting with a radius of 35 meters and increasing by 5 meters per revolution. The problem requires expressing the speed and position of the car as functions of time in polar vector form. The solution involves assuming constant angular momentum and recognizing that the radius is a function of the angle, specifically increasing uniformly with each revolution.
