[VolsDoll82]

Homework Statement

Question 1:
Vf = Vo + at
Find Vo

Question 2:

P1V1 = P2V2
Find V1

Homework Equations

The Attempt at a Solution

Vo = at - vf

I'm new to taking Physical Science. Could someone help me on understanding how to solve the above problems. I got stuck on the second one. Thanks.

i can't understand what you are asking

 

[VolsDoll82]

The question is Vf = Vo + at
I got to find Vo

 

[cupid.callin]

Ummm ... just rearrange them?

 

[VolsDoll82]

Vo = at - vf

is what I got by isolating variables.

 

[cupid.callin]

Rearrange correctly

it must be: Vo = Vf - at

 

[VolsDoll82]

Rearrange correctly

it must be: Vo = Vf - at

Thanks so much. :)
