Answer:
For up to 5.5 s after the golf ball is hit, its height is increasing
The golf ball is in the air for 11 s
The maximum height of the golf ball is 150 m.
Step-by-step explanation:
we know that
The graph shown a vertical parabola open downward
The vertex is a maximum
The vertex is the point (5.5,150) ---> that means
For t=5.5 s, the height of a golf ball is h=150 m
<em>Verify each statement</em>
case A) For up to 5.5 s after the golf ball is hit, its height is increasing.
The statement is true
For the interval (0,5.5) ------> the height is increasing
For the interval (5.5,11) ------> the height is decreasing
case B) It takes 11 s for the golf ball to fall to the ground after reaching its maximum height
The statement is false
It takes 5.5 s for the golf ball to fall to the ground after reaching its maximum height
case C) The golf ball is in the air for 11 s
The statement is true
For t=11 s the golf ball fall to the ground (h=0)
case D) The maximum height of the golf ball is 150 m.
The statement is true
The maximum height of the golf ball is at the vertex of the parabola
The vertex is the point (5.5,150)
case E) The golf ball's speed is 11 m/s
The statement is false
