Phuong & Chi
For this lesson, I actually got help from my teacher, who is amazing at explain theories. I'll first show you this really cool examples and explain everything again if ou feel tired waiting for the video to load :D
Example
This is the example of a monkey and a hunter, which shows you the science behind projectiles: On Earth, particles in free fall accelerates at a=9.81ms^-2
Theory
My teacher explaining the theory behind projectiles
Example on projectiles
Some examples will be given to help you with other excercises later on

? 5.00 ms^-1 0 ms^-1 -9.81 ms^-2
=> v^2 = u^2 +2as
=> 0 = (5.00)^2 + 2x9.81xs
=> 0 = 25 - 19.6s => s = 25/19.6 = 1.28 (m)

0 m 5.00 ms^-1 -9.81 ms^-2 ?
=> s = ut + 1/2at^2
=> s = 5t - 4.9t^2 => t = 1.02 (s)
=> Range: 1.02 x 8.66 = 8.83 (m)
