If you want to double its total energy, you could double the mass. double the force constant (spring constant) of the spring. double both the mass and amplitude of vibration. double the amplitude of vibration. double both the amplitude and force constant (spring con

Answer 1

Answer:

double the force constant

Explanation:

For this exercise we see that the unit mass to the spring executes a simple harmonic motion, the maximum mechanical energy is

             Em = ½ k A²

where A is the range of motion

To double the energy we must increase the amplitude or the spring constant

Therefore, to double the total energy we must increase the amplitude by an amount √2

or we can increase the spring constant to double

The correct answer is to double the force constant
