A block of mass m is suspended by a vertically oriented spring. If the mass of the block is increased to 9m, how does the frequency of oscillation change, if at all? Equation: k W m O The frequency would be one-third of its initial value. O The frequency would be one-half of its initial value. O The frequency would be three times its value. O The frequency would be nine times its initial value. O The frequency would be unchanged.The graph below represents the simple harmonic motion of a mass m = 3.72 kg object. What is the potential energy, U, of the object at t = 0.22 s? Note that the angular frequency, W = 4 because the period, I, is 8.0 s (from the graph) and the amplitude *m = 0.60 m (also from the graph). Please round your answer to three decimal places. x (m) 0.60 2 6 10 t (s)
