This is an interactive homework problem for introductory physics students relating to motion in two dimensions. Two boys, at a distance 63 meters apart, are playing catch. Given the initial speed and angle of projection of the thrown ball, how far must the catcher move to catch it? A user-activated "help" sequence is provided for each step of the problem-solving, from conceptual analysis through quantitative calculation.  To promote critical thinking, immediate feedback is received for both correct and incorrect responses.  This item is part of a larger collection of interactive homework problems for introductory physics.
Editor's Note: This problem goes well beyond the formulas to help learners separately analyze both the x and y components of motion before they plug in numbers.

4. The Physical Setting

4F. Motion
  • 9-12: 4F/H8. Any object maintains a constant speed and direction of motion unless an unbalanced outside force acts on it.

9. The Mathematical World

9B. Symbolic Relationships
  • 9-12: 9B/H2b. Symbolic statements can be combined to look for values of variables that will satisfy all of them at the same time.
  • 9-12: 9B/H5. When a relationship is represented in symbols, numbers can be substituted for all but one of the symbols and the possible value of the remaining symbol computed. Sometimes the relationship may be satisfied by one value, sometimes by more than one, and sometimes not at all.

Topic: Kinematics: The Physics of Motion
Unit Title: Motion in More Than One Dimension

This interactive problem goes well beyond the formulas to help learners separately analyze both the horizontal and vertical components of motion in a ball-throwing scenario......before they attempt any math. Great scaffolding is provided from conceptual reasoning through calculation, with immediate feedback for correct and incorrect responses. It also addresses both Math and Language Arts Common Core standards.
