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 0.0713 m, is rolling along a conveyor belt which is moving at 1.44 m/s and starts out 9.02 m from the finish line. The second ball has a radius of 0.0428 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? 19.2 rad/s Number #1n 12.8 rad/s Number #2
