A cyclist starts from rest and rides in a straight line, increasing speed so that her wheels have a constant angular acceleration of 2.0 rad/s2 around their axles. She accelerates until her wheels are rotating at 8.0 rad/s. If the radius of a tire is 0.32 m, determine how far has the cyclist traveled?
