a).Define the tem angular velocity.
b).A body moving with uniform angular velocity is found to have covered an angular distance of 170 radians in t seconds. Thirteen seconds later it is found to have covered a total distance of 300 radians .Determine t. c).Figure 8 shows a body of mass m attached to the centre of a rotating table with a string whose tension can be measured. The device for measuring tension is not shown in the figure).The tension on the string was measured for various values 0of angular velocity,w,.The distance r of the body from the centre was maintained at 30cm.
