In a football game, a defensive player jumps up to block a pass by the opposing team's quarterback. The player bats the ball downward with his hand at an initial vertical velocity of -51 ft/sec when the ball is 7 ft above the ground. How long do the defensive player's teammates have to intercept the ball before it hits the ground? The model for an object that is launched is on the whiteboard. The topic for the lesson is the quadratic formula.
