The energy of an isolated system oscillating along the -axis is given by the following equation: E equals open parentheses 3 kg close parentheses v subscript x superscript 2 plus open parentheses 48 straight J over straight m squared close parentheses x squared What is the period (in s) of the oscillation?

T = 1.57 seconds

Explanation:

The interpretation of the question is:

What is the period of the oscillation?

Now; the actual energy of the linear oscillationis:

The first part is used in solving the kinetic energy and the second part is used in solving the potential energy, it is in the potential part that the information about the period is hidden.

So, let go by the potential part by comparing them with our given question:

There is need for the mass of the oscillating body, so we take the kinetic part and then compare with our given question:

m = 6kg

Substituting m= 6 kg in the equation above; we have:

Using;

to determine the period

T = 1.57 seconds

a) electrical > light, sound, and thermal< < < <

) the mechanical energy of the firefighter moving.< < < < a) electrical > light, sound, and thermal< < < <

c) both a and b.
