Question

Problem 12d

Answer 1

Given information

There are one sphere and one cylinder both have the same mass and the same radius.

Step-by-step explanation

Step 1.

Moment of inertia of an object determines the resistance for the acceleration during the rotational motion of the object.

The rotational kinetic energy of an object is

 

Here, is the rotational kinetic energy, is the moment of inertia and is the angular velocity.

Therefore, the rotational kinetic energy is directly proportional to the moment of inertia of an object, so the object with greater moment of inertial will have greater rotational kinetic energy.
