A basketball player throws a ball upward from her hands, which are 5 feet above the ground. The basketball reaches a maximum hei
1 answer:
The ball initially goes up then reaches a maximum height from which it
returns downwards and stops in the basket.
Please find attached the graph that represents the relationship between the height of the ball and time.
Reasons:
- The initial height of the basketball = 5 feet
- The motion of the basketball is a parabola, which is concave downwards.
- Given that the basket ball becomes stuck in the net and that the net is higher than 5 feet, we have that the position of the ball after it comes to rest will be higher than the initial position.
Therefore;
The graph of the motion of the ball representing the relationship between he height of the ball and time is as presented in the attached graph crated with MS Excel.

Let us assume base of the window = b feet.
Height is 3 feet less than base, that is = (b-3).
Given area of the triangle = 20 feet square.
We know formula for area of a triangle:
Area = × Base × Height
Plugging values in formula, we get
20 =
Factoring quadratic, we get
=0
b+5=0
b=-5
b-8=0
b=8.
For base we can take only positive value.
<h3>Therefore, base of the triangle = 8 feet and height = 8 -3 = 5 feet.</h3>
