Mass Distribution & Energy

DoNow: A 1 kg ball is rotated on a 2 m string in a horizontal circular path with a constant tangential speed of 5 m/s for 10 seconds.
a. Determine the angular or rotational speed of the object in rad/s.
b. Calculate the distance the object travels during the 10 seconds.
c. Calculate the centripetal acceleration of the ball.
d. List possible changes that would create a non-zero angular acceleration of the ball.
(notes)

AIM: I can describe kinetic energy in rotational terms and the variables that affect rotational inertia. I can identify the rotational inertia equations for at least two different distributions of mass systems.
