Question
Is my work correct? The main question asks for the rotational inertia of the slab 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. Notice that there are multiple trials. Select the trial with the number that is closest to your birth month. SPEED Normal TRIAL Change 1 1. Make measurements and calculations to determine the rotational inertia of the slab (including the objects on the slab). Explain your process and results below. BIU E E E E Score: 0/5 2. Describe the major assumptions you made during your process. BIU E E E E Score: 0/5 3. Do you think the actual value of the rotational inertia of the slab (with the objects on it) is more likely to be greater than your value, or less than your value? Support your assertion. BIU E E E
