An M = 12.3 kg mass is suspended on k = 273000 N/m spring. The mass oscillat up-and-down from the equilibrium positi Yeq = 0 according to y(t) = A sin(wt + $0). Calculate the angular frequency w of t oscillating mass. Answer in units of s 8-¹. At time to = 0 the mass happens to be yo = 19.8 cm and moving upward at veloci v0 = +58.4 m/s. (Mind the units!) Calculate the amplitude A of the oscillati mass.
