Which of the following is an example of an object with elastic potential energy?

C. a stretched rubber band  

Explanation:

A. A wind toy is  unwounded so, it cannot have elastic potential energy. Hence, it’s a wrong answer

B. When a basket is placed on ground, it is in steady state. So, it cannot have any kind of energy. Hence, it’s also wrong answer.

C. Stretched rubber band has elastic potential energy because it will do work when it will be released. So, it’s a right answer.

D. It’s wrong answer because “C” is right answer.

Hence, “C” is the correct answer.

50 inches should be the resultant vector
