A solid uniform-density sphere is tied to a rope and moves (without spinning) in a circle with speed 7 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 6 kg, and the radius of the sphere is 0.70 m.

(a) What is the angular speed??

Angular speed = radians/s

(b) What is the rotational kinetic energy of the sphere?

Krot = J

(c) What is the total kinetic energy of the sphere?

Ktotal = J
