hi..(adsbygoogle = window.adsbygoogle || []).push({});

does anyone now how to solve this problem

A wagon wheel 0.7m in diameter consists of a thin rim having a mass of 7kg and six spokes each having a mass of 1.4kg. Determine the moment of inertia of the wagon wheel for rotation about its axis

and this problem

A 0.18-kg yo-yo consists of two solid disks of radius 12cm joined together by a massless rod of radius 1.00 cm and a string wrapped around the rod. One end of the string is held fixed and is under constant tension T as the yo-yo is released. Find the acceleration of the yo-yo
