Consider the spring mass damper system shown below. k W m x(t) The forces of the spring and damper are represented by Fspring = kx and Fdamper = -bx' respectively, where k is the spring constant and b is the damping coefficient. The mass has an initial displacement +1 m and velocity 0 m/s. 1. Use Newton's 2nd Law of Motion to derive an ODE to describe the mass's motion. 2. Find x(t) for m = 2 kg, b = 1 N s/m and k = {0.1,0.3,0.5} N. m. What happens when the stiffness of the spring is being increased?

Question
Consider the spring mass damper system shown below.
k
m
x(t)
The forces of the spring and damper are represented by Fspring = -kx and Fdamper = -bx' respectively, where k is the
spring constant and b is the damping coefficient. The mass has an initial displacement +1 m and velocity 0 m/s.
1. Use Newton's 2nd Law of Motion to derive an ODE to describe the mass's motion.
2. Find x (t) for m = 2 kg, b = 1 N s/m and k = {0.1,0.3,0.5} N. m.
What happens when the stiffness of the spring is being increased?
