Analysis

12. Did your graph support the statement that the time for a projectile to reach its highest point is equal to the time for the projectile to fall back to earth? Explain.

13. The flight of the projectile can be described by the equation h = vt - 16t², where h = height (distance), t = time, and v = initial upward velocity. What was the initial upward velocity of the rocket?

14. Use the formula h = vt - 16t² to determine how long the rocket should have been at the middle of it's flight. Show your work on the lines below. Then check your work against your data of how long the rocket actually stayed in the air and what its height actually was at the middle of its flight.

15. The height of the rocket can also be described by the function h(t) = vt - 16t². find the height of the rocket after 3 seconds. Then, divide the polynomial in the function by t - 3 to illustrate the remainder theorem. Show your work on the lines below. Then check your work by tracing your graph on the TI-82 to find the value y when x = 3.
