Thank you very much. Hopefully this will help me with the rest of my assignment because the rest of the problems are just like this.
you are right i forgot to place the negative sign in front of the 16. In what way will the change the equation.
h=-16t^2+64t+80
A ball is hit upward from the top of an 80 foot building with an initial velocity of 64ft per second. The height (h) of the ball after t seconds of flight is given by the quadratic equation h=16t^2+64t+80
What is the height of the ball two seconds after its hit?
how long will it take for the ball to reach the ground?
can someone walk through this for me. I have several other questions like this to do so hopefully I will understand if I see how it is done. Your information/feedback is greatly appreciated.
