1. The ball has translational energy only
2. The ball has rotational energy only
3. Both 1 and 2
4. Neither 1 nor 2

Answer 1

Correct Answer - Option 3 : Both 1 and 2

CONCEPT:

• Rolling motion: Rolling is a type of motion that combines rotation motion and translation motion of that object with respect to a surface.

EXPLANATION:

• Rolling motion: Rolling is a type of motion that combines rotation motion and translation motion of that object with respect to a surface.
• So in a rolling motion, the body translates as well as rotates.
• Hence the correct answer will be option 3.
