Compare the potential and kinetic energy of the system.

I need the calculations and the uncertainty in the answers.

Calculate the potential energy Epot from eq.1. The error of Epot is due to the error of k and can be calculated easily since the relative error 6Epot/Epot is the same as the relative error 6k/k. Calculate the kinetic energy Eokin from eqs.2 and 3. The error of Ekin is due to the error of vo. Since Eokin depends on the square of Va, we have to remember that the relative error 6Ekin/Ekin is twice the relative error ova/v0. Fo pot = 1/2 KX2 (1)E kin 1/2 meff Vo (2) =meff = m + ms/ 3 (3)
