Question 9 10 pts 9)A solid disk with a c value of 0.5 about its center and a partial disk with a c value of 0.89 about its center both start at rest at the top of the same incline which has an inclination angle of 30 degrees anda length of 33 meters. If they both rolll without slipping down the incline, how much longer, in s, does the partial disk take to reach the bottom of the incline?
