Question

Jack launches a toy rocket from a platform. The height of the rocket in feet is given by h(t)=-16+t^2 + 112t + 60 where T represents the time in seconds after launch. What is the appropriate domain for this situation?

Answer 1

SOLUTION:

Case: Trajectory equations

Method:

The right graph is:

The domain for the function for the parabola is:

$(-\infty,\infty)$

But because the launch starts from a platform (0, 60) and it lands on the ground (7.5, 0)

The appropriate domain for this situation is:

Final answer:

$0\leq t\leq7.5$
