Question
A solid uniform-density sphere is tied to a rope and moves (without spinning) in a circle with speed 9 m/s. The distance from the center of the circle to the center of the sphere is 1.7 m, the mass of the sphere is 5 kg, and the radius of the sphere is 0.75 m.
What is the angular speed ?

Answer:
angular speed = 5.29 rad/s
Explanation:
For circular motion, the velocity, v, is related to the radius of the circular motion, r, and the angular speed, w, through,
v = rw
9 = 1.7w
w = (9/1.7) = 5.29 rad/s
Hope this Helps!!!
