the radus if the rear wheel of bicycle is twice that of the front wheel. When the bicycle is moving . The angularspeed of the rear wheel comparedto thatof the front is |

Answer» Greater ` orm_(r)r_(r)^(2) Omega_(r) = m_(f) r_(f)^(2) Omega_(f)` Wherethe subscriptsr and f denotethe rearand front. ` m(2r_(f))^(2) Omegar = mr_(f)^(2) Omega_(f) [r_(r) = 2r_(f) ` (Given)] ` therefore4Omega_(r) = Omega_(f)or Omega_(r) = (Omega_(f))/4 ` Hence, the ANGULARVELOCITY of rear wheelwill be smallercomparedto frot wheel. |
