Equations can be used to solve for acceleration

Linear motion consists of 2: constant velocity motion with constant velocity and uniformly accelerated motion with constant acceleration

• An equation of uniformly accelerated motion

V = vo + at or vf = vi + at

Vt² = vo² + 2a (x-xo)

x = distance on t

vo / vi = initial speed

vt / vf = speed on t / final speed

a = acceleration

Acceleration is a change in speed within a certain time interval

a = Δv / Δ t

The velocity graph with respect to time (v-t) in this motion will be in the form of sloping straight lines with a gradient of tan θ = a

For acceleration that is positive (a> 0) is called accelerated motion, the graph is sloping upward, while for acceleration that is negative (a <0) is called slowed down motion, the graph is sloping downward

We complete the available answer choices

t = delta v over a.

vf = at - vi

a = d over t.

vi = vf - at

v = a over t.

vf = at + vi

a = delta v over t.

From the general equation of uniformly accelerated motion above, what is appropriate is:

1. t = delta v over a ---> can be used, a = v / t

2. vf = at - vi ---> cannot be used, it should be vf = vi + at

3. a = d over t .---> d = displacement has the formula: d = v x t, so this 3rd equation cannot be used

4. vi = vf - at ----> can be used

5. v = a over t ----> cannot be used, it should be v = a x t

6. vf = at + vi ---> can be used

7. a = delta v over t ----> can be used

So the equation that can be used to find acceleration is

answer: ask

step-by-step explanation:

∠1≅∠2 by the alternate exterior angles theorem.

step-by-step explanation:

given, a ∥ b and ∠1 ≅ ∠3 .we have to prove that e ∥ f

we know that ∠1≅∠3 and that a || b because they are given. we see that by the alternate exterior angles theorem. therefore, ∠2≅∠3 by the transitive property. so, we can conclude that e || f by the converse alternate exterior angles theorem.

we have to fill the missing statement.

transitivity property states that if a = b and b = c, then a = c.

now, given ∠1≅∠3 and by transitivity property ∠2≅∠3 .

hence, to apply transitivity property one angle must be common which is not in result after applying this property which is ∠1.

the only options in which ∠1 is present are ∠1 and ∠2, ∠1 and ∠4

∠1 and ∠4 is not possible ∵ after applying transitivity we didn't get ∠4.

hence, the missing statement is ∠1≅∠2.

so, ∠1≅∠2 by the alternate exterior angles theorem.
