To solve the problem step by step, we can follow these steps: ### Step 1: Understand the Problem We have a body falling freely under gravity. It passes two points A and B, which are 20 meters apart vertically, in a time of 2 seconds. We need to find the height (H1) above point A from which the body was released. ### Step 2: Define Variables - Let \( H1 \) be the height from which the body is released to point A. - Let \( H2 \) be the height from which the body is released to point B. ...
