Brings me to my next problem which is:
I know that to solve "v" out of s=v*t I need to isolate v on the right side of the equation first so I remove t from there by dividing v*t/t and doing the same on the left side s/t
That leaves me with s/t=v
So v= s/t
But what about this one:
Solve V out of p=m/v?, it's supposed to be V=m/p but I can't figure out how to do it when it's put like that
S=vt
We see multiplication before the v and the t. You undid this operation by dividing (this is inverse operations).
P=m/v
We see m being divided by v. We need to undo division so we use the inverse operation to multiply both sides by v
P*v= (m/v)*v
P*v=mv/v
P*v=m
Now we see multiplication between the p and the v. We need to use the inverse operation and divide both sides by p.
(P*v)/p=m/p
V=m/p
