A body moves along a circular path of radius 15 cm . It starts from a point on the circular path and reaches the end of diameter in 3 second. The angular speed of the body in rad / s is

Step-by-step solution

Let r be radius, Circumference =2 , Half the circle is covered, Distance covered = r=15 r ...(given, r =15 ~cm ) Speed = distance time = 15 3 =5 Angular speed, = v r = 5 15 = 3 rad / s
