What two quantities are crucial to quantifying the translational kinetic energy of an object?

Moment of inertia and angular velocity.

Explanation:

The translational kinetic energy of an object is possessed when the object is showing rotational motion. It can be given by the formula as :

Here,

I is the moment of inertia of the object

is the angular velocity of the object

So, the translational kinetic energy of an object is given by moment of inertia and angular velocity of the object. Hence, this is the required solution.

there are no contact forces mentioned on the list of choices that you've provided.
