I need a solution of this structural dynamics problem?

A mass with mass 1 is attached to a spring with spring constant 64 and a dashpot giving a damping

16. The mass is set in motion with initial position 7 and initial velocity -10. (All values are given

in consistent units.) Find the position function x(t) and plot this from t=0 to 10. What kind of

motion is this?
