Consider a 7 kg ball with a radius of 08bullm and rotating

Question

Compute each part of given question:

Question: Consider a 7 kg ball with a radius of 0.8•m and rotating about an axis passing through its center.

Part I: What is its rotational inertia?

kg•m²

Part II: Suppose the ball is rotating counterclockwise and slowing down with a rotational acceleration of 4rad/s². What is the net torque acting on the ball?

N•m

Part III: Suppose the torque you found for the last part is being produced by a force applied at a point 0.7m from the axis. If the direction of the force is perpendicular to a line from the axis to that point, what is the magnitude of the force?

N
