Physics – Vuthy

A firework goes flying up into the air from the ground and reaches a maximum height of 40m (and falls back down to the ground). What is the total time it stays in the air?

During, Physics class, we were introduced to kinematic equations and solving this kind of questions. This new concept is very useful to understand how objects moves, relevant to time, distance, accelerations and velocity.
With three essential equations:

$a = \frac{v_{f}-v_{i}}{t}$
$d = v_{avg} \times t$
$v_{avg} = \frac{\left ( v_{f} - v_{i}\right)}{2}$

We can use algebra rules and formed into four kinematic equations:

$v_{f} = v_{i} + at$

$d = \left ( \frac{v_{i} + v_{f}}{2} \right ) \times t$

$d = v_{i}t +\frac{1}{2}at^{2}$

$v_{f}^{2} = v_{i}^{2} + 2ad$

In kinematic problems questions, we would need to use one of the equation to solve the problems.

About Me

console.log(”Hello, I’m Vuthy”);
I just wrote a Javascript code that prints my name.

I am a 16-year old student at Liger Leadership Academy in Phnom Penh, Cambodia however I was born and raised with my lovely family in a small town of Kampong Thom Province, a land of beautiful rice fields. I believe that I can make a difference as a change agent.

My life changed forever when I received a full scholarship to study at Liger Leadership Academy, an institution grounded in projected-based learning.

Because of this opportunity, I now consider myself a developer, engineer, innovator, entrepreneur, and a problem solver. These words encompass the essence of who I am. Even though I have many passions, I still have an open mind and accept new experiences and challenges, even if I fail. I do not fear failure and learn from my mistakes.
