Answer the following questions for the given problem:

A ball is thrown up into the air. The ball’s height , h (in feet), from the ground is modeled by

h(t) = -16t2 + 64t +5, where t is measured in seconds.

Before answering these questions, think about the practical meaning of the vertex, y intercept and x intercepts, and how they apply to this problem.

1. What is the height of the ball at its highest point?

2. How many seconds does it take the ball to reach its highest point

3. What is the practical meaning of the y-intercept?

4. What is the height of the ball 1.75 seconds after it is thrown?

5. How many seconds does it take the ball to land on the ground?
