To solve the problem step by step, we will follow the physics of free fall and the equations of motion. ### Step 1: Understand the problem A ball is dropped from the top of a building and takes 0.5 seconds to clear a window that is 4.9 meters high. We need to find the height of the building above the window. ### Step 2: Identify the relevant equations We will use the following equations of motion: 1. \( s = ut + \frac{1}{2} a t^2 \) ...
