Homework Statement
We're working with logarithms of base 3, and log(4)=a and log(7)=b.
The goal is to put log(21) in terms of a and b. For example, take the log(112). It's the same thing as 2a+b since 4*4*7 = 112.

Did I phrase the question poorly. If so my apologies.
It's a pig on a string that is hanging from the ceiling. It's spinning around, but not fast enough that it spins completely horizontally.
Homework Statement
This is me paraphrasing. It's about uniform circular motion. The question involves a pig on a string dangling below a motor. It rotates in a circle below the horizontal.
Resolve the tension vector into components. The vertical component of tension is equal to the...
