Question

A spring for which stiffness k=700 N/m hangs in a vertical position with its upper end is fixed. A mass of 7
kg is attached to the lower end. After coming to rest, the mass is pulled down 0.05 m and released. Find the
resulting motion of the mass, neglecting air resistance.?

Answer 1

Answer:

A spring for which k=700N/m hangs in a vertical position with its upper end fixed. A mass of 7 kg is attached to the lower end. After coming to rest a mass, is falling down 0.05 m and released. Find the displacement as a function of time if the damping force is 0.25 of velocity. fummare
