A 0.175 kg mass on a table is attached to a horizontal spring with a spring constant of 155 N/m. Ignore all friction and air resistance in this problem (i.e. assume no non-conservative forces act on the system) At some time you make a measurement of the mass and find that it is moving at a speed of 0.815 m/s and is 0.03 m from equilibrium. Find the amplitude of the oscillation.
