A spring with spring constant k = 100 N/m is compressed by 0.1 meters. What is the potential energy stored in the spring in Joules?

A. 0.5 J — The potential energy stored in a spring is given by one half k x squared. Substituting the values, we get one half times 100 times 0.1 squared, which is 0.5.

$A spring with spring constant k = 100 N/m is compressed by x = 0.1 m . What is the potential energy stored in the spring in Joules?$

A. $0.5 J$
B. $1 J$
C. $5 J$
D. $0.1 J$

Show correct answer & step-by-step solution

Correct answer: A — $0.5 J$

Solution

The potential energy stored in a spring is given by U = \frac{1}{2} k x^{2} . Substituting the values, we get U = \frac{1}{2} \times 100 \times (0.1)^{2} = 0.5 J .
