K. E. Is 1/2 multiply by mass x velocity square
M is 5kg, v is 4m/s
1/2 x5x4x4 equals 40joules.
For any equation,

assume solution of a form, 
Which leads to,

Simplify to,

Then find solutions,

For non repeated real root y, we have a form of,

Following up,
For two non repeated complex roots
where,

and,
the general solution has a form of,

Or in this case,

Now we just refine and get,

Hope this helps.
