Complete Question
A field mouse trying to escape a hawk runs east for 5.0m, darts southeast for 3.0m, then drops 1.0m down a hole into its burrow. What is the magnitude of the net displacement of the mouse?
The values is![s = 7.49 \ m](/tpl/images/0737/9090/659bf.png)
Explanation:
From the question we are told that
The distance it travels eastward is![x = 5.0 \ m](/tpl/images/0737/9090/1ceba.png)
The distance it travel towards the southeast is![l = 3.0\ m](/tpl/images/0737/9090/e3194.png)
The distance it travel towards the south is![z = 1 \ m](/tpl/images/0737/9090/f9643.png)
Let x-axis be east
y-axis south
z-axis into the ground
The angle made between east and south is![\theta = 45^o](/tpl/images/0737/9090/f3b3a.png)
The displacement toward x-axis is
The displacement toward the y-axis is
Now the overall displacement of the rat is mathematically evaluated as
