Heeyy, I could reeallly use your help answering this question!(:
1. A baseball is thrown with a vertical velocity of 50 ft/s from an initial height of 6 ft. The height h in feet of the baseball can be modeled by h(t)=-16t^2+50t+6, where t is the time in seconds since the ball was thrown. It takes the ball approximately______ seconds to reach its maximum height.
2. To the nearest foot, what is the maximum height that the ball reaches?
3. A player hits a foul ball with an initial vertical velocity of 70 ft/s and an initial height of 5 feet. The maximum height reached by the ball is____ feet.

Have you taken any calculus?

anonymous · Answer

No, I'm in Algebra 2.

anonymous · Answer

ok. The maximum height of the ball thrown is when the velocity=0

anonymous · Answer

So, it should be the maximum of your function

anonymous · Answer

What would that be though? I don't understand it.. Haha
