Answer with Step-by-step explanation:
Let a mass weighing 16 pounds stretches a spring feet.
Mass=
Mass=
Mass,m= Slug
By hook's law
A damping force is numerically equal to 1/2 the instantaneous velocity
Equation of motion :
Using this equation
Auxillary equation
Complementary function
To find the particular solution using undetermined coefficient method
This solution satisfied the equation therefore, substitute the values in the differential equation
Comparing on both sides
Adding both equation then, we get
Substitute the value of B in any equation
Particular solution,
Now, the general solution
From initial condition
x(0)=2 ft
x'(0)=0
Substitute the values t=0 and x(0)=2
Substitute x'(0)=0
Substitute the values then we get
