  • Draw a sketch of distance vs. time when driving at a constant speed.
  • Watch this video:
  • Draw a sketch of height vs. time for the rocket.
  • For each graph, what is the shape?  What kind of relationship is it?
  • How would the graph of the rocket change if it went faster? slower?
  • How would the graph of the rocket change if it started on top of a platform?
​

  • For the most basic linear relationship and the most basic quadratic relationship:
    • make a table of values
    • plot the points and make a graph

Answer this question, and discuss how you solved it with your teacher:
If a projectile is shot vertically upward from the ground with an initial speed of 100 feet per second (neglecting air resistance) its height, h feet, above the ground t seconds after launch is given by the equation:
​After how many seconds will the projectile be 50 ft above the ground?  (Give your best estimate)
