A hollow sphere of radius 30 CM is released from rest on a rough inclined plane. The friction is enough to prevent any slipping. Find the angular velocity (in rad/s) of the sphere, when it descends through a vertical height of 3 CM |

An shaped thin uniform rod of total length
is free to rotate in a vertical plane about a horizontal axis at
as shown in Figure.The bar is released from rest. Neglect air and contact friction. Determine the angular velocity (in rad/s) at the instant when it has rotated through
and reached the dotted position as shown. (Take
1/3m)
