A hollow spherical shell has mass 8.35 kg and radius 0.225 m. It is initially at rest and then rotates about a stationary axis that lies along a diameter with a constant acceleration of 0.885 rad/s^2. Required:
What is the kinetic energy of the shell after it has turned through 6.00 rev?

K = 9.41 J

Explanation:

The kinetic energy of a spherical shell is given as:

where I = moment of inertia and

ω = angular velocity

Let us find I:

For a hollow sphere:

where M = mass = 8.35 kg

R = radius = 0.225 m

Let us find ω:

Since angular acceleration is constant:

Therefore, its kinetic energy is:

well, you would divide 135 by 33 to get your answer. then that is how many seconds it would take. boardman should fly about 132 m or 4.090909090909091 seconds.
