Devise a grapher simulation and use it to support the answer analytically.
Answer to Problem 17E
The bullet will return on moon’s surface after 320 seconds and on earth’s surface after 52 seconds.
Explanation of Solution
Given:
The bullet fired straight from the surface of moon will reach the height of
On earth in the absence of air the height would be
Calculation:
First it is required to draw the graph of height when the bullet fired from moon.
The graph of the function
In the above graph the horizontal axis shows the time in seconds and vertical axis represents the height that bullet attain.
The height is maximum at
Analytical method When the bullet is fired from moon’s surface the height is
Substitute
This gives two solutions
