Question

A series of object are being rotated. The same net torque is being applied to each object. Rank the object in order of the resulting angular acceleration (1=lowest). An object consisting of two objects connected by a massless rod. Each object has a mass of 2M and is a distance R from the axis of rotation.

a) A hoop spinning about its center. Total mass is M and the radius is R.

d) A solid disk spinning about its center. Total mass is M and a radius of R.

c)A hoop spinning about its center. Total mass is 2M and a radius of R.

Explanation / Answer

angular acceleration of d>a>c

object with 2 object and massless road have lowest angular acceleration.
