with
Homogeneous Solution
edit
The solution to a L2-ODE-CC with two complex roots is given by
where
Solving for A and B
edit
first initial condition
second initial condition
so the solution to our L2-ODE-CC is
Solution to R2.6
edit
After solving for the constants and we have the following homogeneous equation
Characteristic Equation and Roots
edit
We have a real double root
Homogeneous Solution
edit
We know the homogeneous solution to a L2-ODE-CC with a double real root to be
Assuming object starts from rest
,
Plugging in and applying our first initial condition
Taking the derivative and applying our second condition
Giving us the final solution
Solution to this Equation
