An object of mass 6.8 kg is attached to an ideal spring of force constant 1720 N/m. The object is set into simple harmonic motion, with an initial velocity of v0 = 4.1 m/s and an initial displacement of x0 = 0.11 m. Calculate the maximum speed the object reaches during its motion. Numeric answer only. The units are m/s – DO not put the units in the answer box only the number.
