Answer:
930.21J
Step-by-step explanation:
The kinetic energy of a solid body that is rotating, is given by:

where I is the moment of inertia and w is the angular velocity.
The moment of inertia for a spherical shell is:

where M is the mass and R is the radius of the sphere. By replacing we have

To calculate w we have to use the equation

where we have taken w0=0 rad/s.
Finally, by replacing I and w we obtain:
