Question

Can some one Plzz help?!!
Activity 1). An archer releases an arrow from a shoulder height of 1.39 m. When
the arrow hits the target 18 m away, it hits point A. When the target is
removed, the arrow lands 45 m away. Find the maximum height of the
arrow along its parabolic path.

Answer 1

the height of the target/from the ground to the target is1.52m

Answer 2

Answer 3

sorry i forgot how to do this

Answer 4

you did it previously

Answer 5

i know the answer is 1.41m
i just need help on how to solve it
Can any one help me please

Answer 6

how do you know the answer is 1.41?

Answer 7

No answer is not 1.41 as the point A which was hit earlier itself is at 1.52 - 0.04 = 1.48 m.

Answer 8

You can make 3 known points,
Point 1 - The point at which the arrow is released. Assume this point as Origin (0,0)
Point 2 - Point A as per the problem. which is (18,0.09)
Point 3 - Where the arrow landed. (45,-1.39)
The try to find the equation of the parabola passing through these 3 points.
You will be closer to your answer

Answer 9

a freind told me ill end up with 1.41

Answer 10

45 meters away from the starting point, or 45 meters further from the already 18m target?
