Question 813887: One of the games at a carnival involves trying to ring a bell with a ball by hitting a lever that propels the ball into the air. When Marc plays this game, the height of the ball is modeled by the equation h(t)=-16t^2+39t. If the bell is 25 feet about the ground, will Marc be able to hit he bell with the ball?
