The distance traveled by the egg after 2 seconds is 19.6 m.
The given parameters:
- <em>Height of the window, h = 40 m</em>
The distance traveled by the egg after 2 seconds is calculated as follows;

where;
- <em />
<em> is the initial vertical velocity of the egg = 0</em> - <em>g </em><em>is acceleration due to gravity = 9.8 m/s²</em>
- <em>t </em><em>is the time of motion, = 2 s</em>

Thus, the distance traveled by the egg after 2 seconds is 19.6 m.
