My mind's running in circles and I have no idea what the heck I'm doing anymore. Please someone make sense of this mess I've created:Suppose you throw a baseball into the air from a starting height . You toss the ball with an upward velocity of ft/s. You can use the equation h=(-16)t^2+vt+s to find the ball's height in feet seconds after it is thrown.

A.) Suppose you toss a baseball directly upward with a starting velocity of 46ft/s from a starting height of 6ft. When will the ball hit the ground?

Then the quadratic formula...

And I get:

which means

I'm positive I've done this wrong.
