<h2>Introduction</h2>Hi ! In this question, I will help you. In this question, you will learn about the fall time of the free fall motion. Free fall is a downward vertical motion without being preceded by an initial velocity. When moving in free fall, the following equations apply:
<h3>The equation for calculating the height (h)</h3>With the following condition :
- t = interval of the time (s)
- h = height or any other displacement at vertical line (m)
- g = acceleration of the gravity (m/s²)
- v = velocity (m/s)
We know that :
- t = interval of the time = 5 s
- g = acceleration of the gravity = 9.81 m/s²
What was asked :
- h = height or displacement at vertical line = ... m
Step by Step :
So, the initial altitude of the parachuter is approximately 123 m (C.)
