Energy in Simple Harmonic Motion

SUMMARY

The total energy of a 1.3 kg object oscillating in simple harmonic motion on a spring with a force constant of 410.0 N/m is calculated using the formula E_tot = (1/2)m(v_max)^2. Given the maximum speed (v_max) of 0.7 m/s, the total energy can be determined without needing to calculate the maximum displacement (x). The total energy is equivalent to both the kinetic and potential energy at maximum displacement, confirming that only one formula is necessary for the calculation.

A 1.3 kg object oscillates with simple harmonic motion on a spring of force constant 410.0 N/m. The maximum speed is 0.7 m/s. What is the total energy of the object and the spring?

Do I just set it up like this:

1/2*410*x^2=1/2*1.3*.7^2 to get the max x
Then do I just add them up

No. Both are equal to the total energy. Use just one of them.

Easier would be to write E_tot = (1/2)m(v_max)^2, since m and v_max is given.
