A spring is compressed by 10 cm by a ball of mass 20 g . What will be the potential energy of a spring if the force constant of the spring is 20 N `cm^(-1)` .

Explanation

To find the potential energy stored in a compressed spring, we can use the formula for the potential energy (PE) of a spring:

\[ PE = \frac{1}{2} k x^2 \]

where:
- \( k \) is the spring constant,
- \( x \) is the compression or extension of the spring.
