1.	A rigid body acquires angular speed of 100 rad s^(-1) after undergoing angular displacement of 600 rad in 12 s. Then the initial angular speed is ……… rad/s
Answer» `8.33` 100 0 50 Solution :`THETA=((omega+omega_(0))/(2))t` `THEREFORE 600=((100+omega_(0))/(2))12` `therefore 100=100+omega_(0)` `therefore omega_(0)=0`
