Well socially we are taught nowadays that we have to dress a certain way we have to act a certain way and we just have to meet criteria to be cool which was always a thing but now its much worse and harder to fit in and when we try to make friends they are too busy with girlfriends boyfriends and their phones to actually speak to you not everyone but most of everyone.
Educationally we are learning that all the knowledge that we ever need is in our pockets half the time and the other half in the palm of our hand and we never leave without it;Our phones.I can't tell you how many times that i have heard someone's kid saying that school is dumb blah blah blah and that i can just search what i need to know which is true but not healthy.
So in conclusion kids have it really easy and are heading down a less social but more social media like road and aren't educating themselves like they should mentally.

Answer:
- time: 1.122 seconds
- range: 10.693 m
- maximum height: 1.543 m
Explanation:
<u>Given</u>:
runner is launched at 30° angle to horizontal at 11 m/s
acceleration due to gravity is g = -9.8 m/s²
<u>Find</u>:
runner's hang time
runner's distance to the landing point
runner's maximum height
<u>Solution</u>:
The (horizontal, vertical) speed components will be ...
(11 m/s)(cos(30°), sin(30°)) = (5.5√3 m/s, 5.5 m/s)
The time of flight can be found from the height formula:
h(t) = 1/2gt² +vt . . . . . . where v is the vertical speed at launch
The time we're concerned with is the time when h(t)=0 and t>0.
0 = -4.9t^2 +5.5√3t = t(-4.9t +5.5√3)
The second factor is zero when ...
t = (5.5√3)/4.9 ≈ 1.122 . . . seconds hang time
__
The distance to the landing point will be the product of horizontal speed and hang time:
d = (5.5 m/s)(5.5√3/4.9 s) ≈ 10.693 m . . . . distance to landing
__
The maximum height can be found from the formula (based on conversion of kinetic energy to potential energy) ...
h = v²/|2g| = (5.5 m/s)²/(2(9.8 m/s²)) ≈ 1.543 m . . . . maximum height
