Answer:
(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=+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)
(2.5,10.5) is the coordinate of A
