A solid wooden cylinder has a mass of 12kg and a radius of 25cm. Itis hung from its cylindrical axis using a steel piano wire.It isobserved that a tangential force of 1.5N is required to "twist" themass through a 20 degree angle. From its position, the mass isreleased and allowed to rotate.
a.) what is the period of the motion?
b.) what is the total mechanical energy of the system?
c.) what is the maximum angular speed of the object? At what pointin the motion does this occur?
*There are two different things using the symbol w here, it happenssometimes, so this is an example of not getting them mixedup.
d) what is the maximum angular acceleration of the object? At whatpoint in the motion does this occur.
