what do all the variables represent? what is used to solve? Does he have a name?
What does d = vit + 1/2at^2 mean?
what do all the variables represent? what is used to solve? Does he have a name?
my teacher gave us all the equations to look up, but I can’t find a good definition.
Distance = (initial velocity * time) + (½ * acceleration * time^2)
D = distance
vi = initial velocity
t = time
a = acceleration = (change in speed ÷ time)
Example:
A car moves at an initial speed of 10 m/s.
The driver presses the accelerator pedal to the ground, causing the car to accelerate at 50 m/s per second for 15 seconds.
What is the total distance traveled by the car during the 15 seconds?
Distance = (10 * 15) + (½ * 50 * 15^2)
Distance = 150 + 5625 = 5775 meters
definition of vitamin
1 variables
d (commonly used s) = distance traveled
vi = initial velocity (it should be vì where ì=1,2,3…)
a = acceleration/deceleration of the object
t = elapsed time
#2 Common Uses
1 – measure one variable when another is known.
2 – only applicable when the acceleration/deceleration is said to be uniform and the object is moving in a straight line.
and acceleration value is applied as positive (+) and deceleration as negative (-)
acceleration ex-5ms-2; 1/2 (+5)t +2.5t
5ms-2 deceleration; 1/2 (-5) t -2.5 t
3 – in solving problems based on projectiles (common use)

#3 Name
it is another “equation of motion”.
Vitamin D is used by the body to absorb calcium. It’s hard to tell if a mother or baby is vitamin D deficient. In the Pacific Northwest, 15 minutes of sun exposure a day should be enough for vitamin D absorption. I live in Canada about an hour from the US border. what I was told. Because it’s such an important mineral for your baby, many doctors prescribe a supplement just to make sure your baby gets enough of it. This is also true for iron in anemic mothers. Our daughter was taking both until she started formula. On days when we were in the sun a lot or needed to supplement with formula, I skipped vitamin D. Otherwise, we were loyal to donating.
Well, since it’s up to you to research, I’m not going to give you the answer.
You’ll find it in thousands of places (possibly using different variables) under “uniform acceleration” or “accelerated motion” or “constant acceleration”.
It’s on Wikipedia’s “Uniform Acceleration” page, for example. With different variables as I said. The specific letters used mean nothing.
Answer 6
This equation represents the path a particle/object takes in time t if it has acceleration a and initial velocity vi. that “i” should be an index (index)
Answer 7
It is the formula for the distance traveled by an object in a given time, when its acceleration is constant.
d = distance traveled
vi = initial velocity of the object
a = acceleration of the object
t = elapsed time

“s” is often used instead of d.
“u” is often used instead of vᵢ. The “ᵢ” stands for initial.
