Question

Two different balls are rolled (without slipping) toward a common finish line. Their angular speeds are shown to the right. The first 25.2 rad /s ball, which has a radius of 0.0613 m, is rolling along a conveyor belt which is moving at 1.94 m/s and starts out 8.72 m from the finish line. The second ball has a radius of 0.0408 m and is rolling along the stationary floor. If the second ball starts out 6.59 m from the finish line, how long does each ball take to reach the finish line? Number #1 14.3 rad /s Number #2 What angular speed would the losing ball have needed to cross the tinish line at the same time as the winning ball? Number rad s
