A juggler is performing her act using several balls. She throws the balls up at an initial height of 4 feet, with a speed of 15 feet per second. This can be represented by the function H(t) = −16t2 + 15t + 4. If the juggler doesn't catch one of the balls, about how long does it take the ball to hit the floor?
