Question

A football is throw by a quarterback to a receiver

Answer 1

(2.5,10.5)

Explanation:

Given that a ball is thrown verically upwards with an initial velocity. We know that the path is a trajectory as a parabola.

From graph we find that horizontal is in yards and vertical is in feet.

WE have to find the coordinates of A

When ball is thrown upward, acceleration due to gravity is -32 ft/s^2

Since height = s=
`ut-16t^2`+h0

we get h0 as initial height.

But without any calculation from the graph we find out these coordinates as

x coordinate = 2.5(since in the middle of 0 and 5)

y coordinate = 10.5(since in the middle of 9 and 12)

Answer 2

(2.5,10.5)

Explanation:

In the abscissa (x), A is in the middle point between 0 and 5:

`x=(0+5)/(2)\\ x=(5)/(2)\\ x=2.5`

In the ordinate (y), A is in the middle point between 9 and 12:

`y=(9+12)/(2)\\ y=(21)/(2)\\ y=10.5`

Then, the coordinates of point A are:

A=(x,y)→A=(2.5,10.5)
