Our Sun has a radius of about 695,800 km and a mass of about 2.0 × 1030 kg, and rotates around its axis about once every 29 days.Calculate the rotational velocity of the Sun. Calculate the linear speed of particles on the outermost portion of the Sun. Calculate the angular acceleration, tangential acceleration, and radial acceleration of the Sun. Calculate the rotational (angular) momentum of the Sun, modeled as a uniform solid sphere. The rotational inertia of a solid sphere is (2/5)MR2. Imagine that without any external objects interacting with it, the Sun were to collapse to the size of a neutron star, with a radius of about 15 km–about the size of Manhattan Island. What would be its rotational inertia when it was finished collapsing? What would be its rotational momentum when it was finished collapsing? In what time interval would the Sun complete one rotation around its axis after it was finished collapsing

Definition Definition Rate of change of angular velocity. Angular acceleration indicates how fast the angular velocity changes over time. It is a vector quantity and has both magnitude and direction. Magnitude is represented by the length of the vector and direction is represented by the right-hand thumb rule. An angular acceleration vector will be always perpendicular to the plane of rotation. Angular acceleration is generally denoted by the Greek letter α and its SI unit is rad/s 2 .
