This is an interactive homework problem for introductory physics students relating to velocity and acceleration. A ball is thrown straight upward and a person 70m away runs to catch it before it hits the ground. Given initial speed of the thrown ball, students are required to determine how fast the runner must go. This problem is accompanied by a Socratic-dialog "help" sequence designed to encourage critical thinking as users do a guided conceptual analysis before attempting the mathematics.
