Find the mechanical energy of a block-spring system with a spring constant of 1.8 N/cm and an amplitude of 2.4cm.

Explanation

To find the mechanical energy of a block-spring system, we can use the formula for the total mechanical energy in a simple harmonic motion (SHM) system, which is given by:

\[ E = \frac{1}{2} k A^2 \]

where:
- \( E \) is the total mechanical energy,
- \( k \) is the spring constant,
- \( A \) is the amplitude of the motion.
