Question 1104536: A ball is thrown vertically upward from the top of a building 96 feet tall with an initial velocity of 80 feet per second. The distance S (in feet )of the ball from the ground, after t seconds is s=96+80t-16t^2.
a. How long does it take for the ball to reach its
highest point?
b. What is the maximum height the ball reaches?
You can put this solution on YOUR website! A ball is thrown vertically upward from the top of a building 96 feet tall with an initial velocity of 80 feet per second. The distance S (in feet )of the ball from the ground, after t seconds is s=96+80t-16t^2.
-----------
Use s(t) = -16t^2 + 80t + 96
=================
a. How long does it take for the ball to reach its
highest point?
The value of t at the vertex, t = -b/2a
---
b. What is the maximum height the ball reaches?
The max is the vertex of the parabola.
