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. If the juggler doesn't catch one of the balls, about how long does it take the ball to hit the floor?

Hint: Use H(t) = −16t2 + vt + s.
7.52 seconds
1.15 seconds
0.47 second
0.22 second
