The ball will land when the height is 0; that's when the ball will hit the ground, right?

So, simply use the quadratic formula(or try to factor it/complete the square

You'll get two solutions, so you pick whichever one is positive(the negative time doesn't make sense in this case)

Its approximately 3.2 seconds, so B.
