Concept explainers

Moment of Inertia

Inertia can be termed as a resistance offered by a body to change its state. A rigid body initially at rest will apply resistance when acted by an external force that tends to change its state of rest or velocity, or a body initially at motion will provide resistance in changing its state of velocity or motion for coming to a state of rest. In other words, Newton's first law of motion describes the law of inertia of a rigid body.

Question

Is my work correct? The main question asks for the rotational inertia of the slab with object on disk

The videos below show a view from above of a non-uniform object (a rectangular slab with objects placed on it) dropped onto a
platform rotating on a low-friction bearing. The mass of the rotating disk is 2.85 kg.
Notice that there are multiple trials. Select the trial with the number that is closest to your birth month.
