A wheel accelerates at a constant rate from 30 rpm to 90 rpm, turning through 8.00 radians in the process. Two persons start at the same place but walk around a circular lake in opposite directions. Their angular speeds are 1.90 x 10-3 rad/s and 3.10 x 10-3 rad/s, respectively. How much time elapses before they meet? Find its angular speed 1.00 s after this process begins.
