Projectile Motion Project (Quiz Grade)
In this project, you will create your own projectile motion word problem to model the
function 𝒉(𝒕) = −𝟏𝟔𝒕𝟐 + 𝒗𝒐 𝒕 + 𝒉𝒐 where t is time in seconds, vo is initial velocity,
and ho is initial height. You will be graded on creativity as well as the accuracy and
completeness of your work.
Directions: and specify the initial height and velocity.
1) Create a situation in which you are throwing/launching/dropping an object. Write
out in a few sentences the situation. Include who, what, where, when and why (BE
CREATIVE! See p. 292 and 298 in your text for models and ideas).
2) Write a quadratic function to model the situation using the initial height and
velocity that you create.
3) Find the axis of symmetry. (SHOW ALL WORK!)
4) Find the vertex. (SHOW ALL WORK!) Interpret in a sentence the meaning of the x
and y values within the context of your problem.
5) State whether your parabola will open upwards or downwards and how you know.
6) Graph your function. Be sure to label the axes and title the graph. You may change
the scale of the axes if you want, or create a graph on the computer.
7) Solve your quadratic equation (approximate if necessary). Interpret the solution
within the context of your problem in a sentence.
8) Draw a picture (separate from your graph) modeling the problem. You can print out
pictures from the Internet or draw freehand.
Please remember to keep your projects school appropriate!
