Question
Transcribed Image Text:A jet flies in a parabolic arc to simulate partial weightlessness. The curve shown in the figure represents the plane's height
y (in 1000 ft) versus the time t (in sec).
a. For each ordered pair, substitute the t and y values into the model y = at2 + bt + c to form a linear equation with three
unknowns a, b, and c. Together, these form a system of three linear equations with three unknowns.
b. Use a graphing utility to solve for a, b, and c.
c. Substitute the known values of a, b, and c into the model y = at2 + bt + c.
d. Determine the vertex of the parabola.
e. Determine the focal length of the parabola.
