Two different balls are rolled (without slipping) toward a common finish line. Their angular speeds are shown to the right. The first ball, which has a radius of 0.0738 m, is rolling along a conveyor belt which is moving at 2.19 m/s and starts out 8.87 m from the finish line. The second ball has a radius of 0.0508 m and is rolling along the stationary floor. If the second ball starts out 5.99 m from the finish line, how long does each ball take to reach the finish line?

one ball is 21.7 rad/s and the other 13.8 rad/ sec
