two tall building are situated 300 m apart . A ball is thrown horizontally from the window of `10^(th)` floor of one building such that it lands in a windo of `3^(rd)` floor of another nuilding. If the vertical distance between the corresponding floors of the building is 5m, find the velocity with which the ball must be thrown .

Explanation

To solve the problem of finding the velocity with which the ball must be thrown horizontally from the 10th floor of one building to land in the window of the 3rd floor of another building, we can follow these steps:

### Step 1: Determine the vertical distance (h)
The vertical distance between the 10th floor and the 3rd floor is given as:
- Height of one floor = 5 m
- Number of floors between 10th and 3rd = 10 - 3 = 7 floors

So, the total vertical distance (h) is:
...
