Spring constant-Find the equation of motion of the mass

Reference no: EM13652325

A mass of 1/4 slug is attached to a spring having a spring constant of 1 lb/ft. The mass is started in motion by initially displacing it 2ft. in the downward direction and giving it an initial velocity of 2 ft/sec in the upward direction. Find the equation of motion of the mass, if the force due to air resistance is -1x'.
