Activity Pages Can SpaceShipTwo fly up to space? Vocabulary • Parabola: The graph of a quadratic equation, which for this project is in the shape of an upside-down capital “U” • Quadratic Equation: The equation that creates a parabola when graphed • Vertex: The maximum (or Minimum) point on a parabola Narrative If a baseball is thrown into the air to another ball player, it will continue moving upward after it leaves the ball player’s hand. The ball will eventually reach a maximum height (which we can calculate), and then drop back down to the other player’s glove. Virgin Galactic’s SpaceShipTwo (SS2) follows a flight profile very similar in nature. Can we figure out how high the spacecraft went? Why, I’m glad you asked!
