Final answer:

To find the initial velocity of the ball passing a window, use kinematic equations for distance along the window and vertical distance, then solve for initial velocity.


Explanation:

The ball's initial velocity can be determined using the kinematic equation:

  1. For the distance along the window: Using the time taken to pass the window and the height, the initial velocity at the bottom of the window can be calculated.
  2. For the vertical distance: Considering the distance from the ground to the bottom of the window, the initial velocity can be determined using the velocity at the bottom of the window as the final velocity.

By solving these two components, the ball's initial velocity can be found for the given scenario.
