A mass gains a speed of 28.2 cm/s when it is released from rest at the free end of a spring that is compressed by 3.20 cm horizontally. If the mass is now connected to the free end of the spring to form a mass-spring system, what is the period of this harmonic oscillator?

Iam on that question know can you tell me the answer i am realy strruglingasap

Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge,    then the following gives us the potential difference,      the formula  may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get    using q = 8.00  × 10⁻¹⁹ c and  δv = 2.00 v, we get    the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.
