Question

v=At^3-Bt where t is time, identify the dimensions defined by A and B

Answer 1

Basically need a way to define velocity by something time cubed - something time.
trying to play around with initial velocity or initial acceleration - the other, but i'm not getting anything that makes any sense

Answer 2

they can be scalar values. I dont understand what you want to ask

Answer 3

I'm supposed to determine what dimensions A and B can be (like say it was N=m*A then A what be defining m/s^2) I just don't know how to define v using something - something else besides Vf-Vo

Answer 4

V=m/s
t=s

so your one is
\[V=A.t ^{3}-B.t\]

\[m/s=A.s ^{3}-B.s\]
the right part must be m/s

so \[A.s ^{3}=m/s\]
\[A=m/s ^{4}\]

B.t=m/s
\[B=m/s ^{2}\]

that ?

Answer 5

I'm going with that because that was the only way I could think to make it make sense, just reiterate the v by making A and B nonsensical just to force them to equal v. (make it non-applicable, but purely a definition)
