Read the real-world situation and substitute in values for the projectile motion formula. Then solve the resulting quadratic equation by factoring to answer the question. How long does it take a rock to hit the ground if thrown off the edge of a 72 foot tall building roof with a downward velocity of 24 feet per second? The rock lands seconds after it is thrown.
