A 2.50-kg object is attached to a spring with a force constant of 4.50 N/m. The object rests on a horizontal surface that has a
viscous, oily substance spread evenly on it. The object is pulled 15.0 cm to the right of the equilibrium position and set into
harmonic motion. After t¡ = 2.00 s the amplitude has fallen to 7.00 cm due to frictional losses in the oil.
