Answer:
Explanation:
From the information given:
The avg. velocity post the window is;
= velocity located at the top of the window
= velocity situated at the bottom of the window
Using the equation of kinematics:
Hence,
To determine the average velocity as follows:
where;
= velocity gained when fallen through the height h.
Similarly, using the equation of kinematics, we have;
Thus, the velocity at the ground is;
