SOLVE STEP BY STEP IN DIGITAL FORMAT A physical spring system follows the equation + ki = 0, with initial conditions (0) = 2 and '(0) = Vo. If it is observed that this system has a period T = π/2 and an amplitude A=2. Find the value of k and vo- Hint: Consider that the physical period si was the ratio T = 2π/w, where is the angular frequency.
