Consider the situation in Quick Quiz 13.4. Is the subsequent total mechanical energy of the object with mass 4m (a) greater than, (b) less than, or (c) equal to the original total mechanical energy?

To determine
How the total energy will change when the mass of the object becomes four times.

Explanation

Given info: The spring is stretched to a displacement A from the equilibrium. The object with mass m is changed to an object with mass 4m.

Explanation:

The total energy in terms of the amplitude of the motion is,

E=12kA2

Since the object starts from rest at displacement A in both the cases, there is no change in the amplitude of the motion
