Solve each equation. If exact roots cannot be found, state the consecutive integers between which the roots are located. 4. 5. 6. 7. 8. 9. GRAVITY Use the formula h(t) = , where h(t) is the height of an object in feet, is the object?s initial velocity in feet per second, and t is the time in seconds. a. Marta throws a baseball with an initial upward velocity of 60 feet per second. Ignoring Marta?s height, how long after she releases the ball will it hit the ground?
