47. (a) We apply conservation of angular momentum: I 1 ω 1 + I 2 2 = ( I 1 + I 2 ) . The angular speed after coupling is therefore () 22 11 2 2 12 3.3kg m 450 rev min 6.6kg m 900 rev min 3.3kg m 6.6kg m 750 rev min. II ωω ⋅+ + == +⋅ + = (b) In this case, we obtain 3.3 kg m 450 rev/min 6.6 kg m 900 rev/min 3.3 kg m 6.6 kg m 450 rev min
