Question

A uniform disk with a mass of 7 kg and a radius of 1.05 m is

rotating with a rotational velocity of 15 rad/s what is the
rotational inertia of the disk?

Answer 1

The rotational inertia of the disk is 3.67 kg * m^2.

Step-by-step explanation:

The rotational inertia of a disk can be calculated using the formula:

I = (1/2) * m * r^2

where:

• I is the rotational inertia
• m is the mass of the disk
• r is the radius of the disk

Using the given values, the rotational inertia of the disk is:

I = (1/2) * 7 kg * (1.05 m)^2 = 3.67 kg * m^2
