# Problem with old and New angular speed help me please

 P: 2,218 Whats changing here is the moment of inertia of the weights. They are originally at distance 1.09m and are contracted to 0.307m. Find this new moment of inertia. Then since momentum is conserved in the system, you can find the new angular speed by: $$I_i\omega_i = I_f\omega_f$$ solved for $$\omega_f$$
 P: 286 Just to concur with whozum: You need to use conservation of angular momentum: $$L_i = L_f$$ Where: $$L = p\times r$$
