Answer:
572
Explanation:
Got it right on Acellus, you take the velocity and divide it by 4 times the length.
Answer:
Mia is correct, but did not show a lot of work.
Explanation:
Mia must explain her answer and give reasoning by using what knowledge she has on the subject.
Here is the answer!!!!!!!
Scientists must have an unbiased type of investigation. These type of science requires three major characteristics for it to be functional and sticked to the truth: they must be impartial, accuarate and truthful. Without these characteristics there is no way forensic science must be treated as science.
Recall the definitions of
• average velocity:
v[ave] = ∆x/∆t = (x[final] - x[initial])/t
Take the initial position to be the origin, so x[initial] = 0, and we simply write x[final] = s. So
v[ave] = s/t
• average acceleration:
a[ave] = ∆v/∆t = (v[final] - v[initial])/t
Assume acceleration is constant (a[ave] = a). Let v[initial] = u and v[final] = v, so that
a = (v - u)/t
Under constant acceleration, the average velocity is also given by
v[ave] = (v[final] + v[initial])/2 = (v + u)/2
Then
v[ave] = s/t = (v + u)/2 ⇒ s = (v + u) t/2
and
a = (v - u)/t ⇒ v = u + at
so that
s = ((u + at) + u) t/2
s = (2u + at) t/2
s = ut + 1/2 at²
