Question
The upward velocity of a rocket is at three different times as
tabulated below, and approximated as polynomial where v is
the velocity in m/s and t is the time in seconds.
v = a¡t² + azt + a3,

Using the Gaussian Elimination Method, solve for the values of
the unknowns of the given system of linear equations. And
determine the value of the velocity when the time is
9 seconds. Show solutions of forward eliminations and
backward substitutions.
