a.
To find: the initial height of the arrow.
a.
Answer to Problem 42E
1.5 meters
Explanation of Solution
Given information:
The graph showing the path of the arrow is:
Calculation:
The y -intercept of the given graph gives the initial height of the arrow.
By observing the given graph it can be said that the y -intercept is
So, the initial height of the arrow is 1.5 meters.
b.
To estimate: the maximum height of the arrow.
b.
Answer to Problem 42E
Approximately 1.6 meters.
Explanation of Solution
Given information:
The graph showing the path of the arrow is:
Calculation:
Consider the given graph,
From the above graph it can be observed that the maximum height is approximately 1.6 meters.
c.
To find:the distance travelled by the arrow.
c.
Answer to Problem 42E
90 meters
Explanation of Solution
Given information:
The graph showing the path of the arrow is:
Calculation:
The x -intercept of the given graph gives the distance travelled by the arrow.
By observing the given graph it can be said that the x -intercept is
So, the distance travelled by the arrow is 90 meters.
