Homework Statement
Which one of the following equations is dimensionally homogeneous?
Where:
F= force (N)
m= mass (kg)
a= acceleration (m/s2)
V= velocity (m/s)
R= radius (m)
t= time (s)
Homework Equations
1. F=ma
2. F=m(V2/R)
3. F(t2-t1)=m(V2-V1)
4. F=mV
5. F=m(V2-V1)/(t2-t1)
The Attempt at a Solution
Through what I can gather from my textbook and the internet, I started by entering what I know. So:
F=ma
becomes:
N=(kg)(m/s2)
From here, I'm not really sure where to go.
F=m(V2)/(R)
becomes:
N=(kg)((m/s2)/(m))
And again, I plug everything in but in my textbook at this point is where they determine if it is or isn't dimensionally homogeneous.
I would really appreciate any guidance on this, I realize it's a super basic question, but you've got to start somewhere! Thank you.
