The graph below shows a crow flying along at a constant speed, carrying a ball. Suddenly, the crow drops the ball. The diagram shows the position of the crow and the ball at five points in time. According to the trend shown by the graph below, at what height was the ball most likely at 3.5 seconds? (2 points)
This question made no sense to me and I don't understand it.
A) approximately 58 m*******
B)approximately 39 m
C)approximately 50 m
D)approximately 30 m
4.9 t^2 = falling distance if initial vertical component of speed was zero
4.9 (3.5)^2 = 60 meters fall
so 60 meters BELOW THE CROW. (you did not say how high the crow was)
that is because if g = 9.8 m/s^2
then in the vertical direction
a = -9.8 m/s^2
v = Vi - 9.8 t where Vi is initial speed up
z = Hi + Vi t - (9.8/2) t^2 where Hi is initial height
Note that if the crow continued on the same level path, the ball hits the ground right under the crow because there is no horizontal acceleration. If you drop a bomb from your airplane, turn.
To answer the question, we need to make observations from the graph and determine the height of the ball at 3.5 seconds.
1) Look at the graph and find the time point that represents 3.5 seconds.
2) Make note of the position of the ball at that time.
3) Determine the height of the ball at that position.
Unfortunately, without the graph or any visual representation, it is difficult for me to provide a specific answer. However, I can break down the steps you would need to follow to find the answer:
1) Look for the data points on the graph that represent the position of the crow and the ball at different points in time. Pay attention to the y-axis, which represents height.
2) Identify the time point that corresponds to 3.5 seconds.
3) Find the corresponding height value on the y-axis at that time point.
4) Determine the height at that position.
If you could provide a visual representation of the graph or more specific details, I would be able to assist you further in finding the correct answer.
