Please help me on this question. Thank u!

For items 4-5, consider the problem statement below:
A 0.10-kg object is attached to a spring with a spring constant of 5 N/m. A damper is attached to the system
such that it exerts a 2 N-force when the velocity is 2 m/s. Moreover, there are no other external forces acting on
the system.
4. Which of the following equations describe the displacement of the mass at any time t? Note that x is the
displacement of the mass and t is the time that the mass is in motion.
A. x = et (A cos 5t + B sin 5t)
B. x = e (A cos 5t + B sin 5t)
