So I was able to figure it out myself. Apparently, this is a pinacol rearrangement (http://en.wikipedia.org/wiki/Pinacol_rearrangement), which would explain many things...namely that we never even covered it in lecture at this point. >.>

A box m = 88 kg is being pulled by a constant force F = 176 N at an angle of θ = 38 degrees.
m = 88 kg
θ = 38 degrees

Ah, that makes sense. I got .125N as a result and this appears to be the correct answer. Still, I'm not entirely sure about part B for this problem. Should I draw a free body diagram for that part?
So this is what I ended up doing:
TSB = (.05kg)(.837)2/(.14)
I got the velocity by doing 2∏*(.28m) / 2.1 seconds
I got an answer of .250N exactly...but apparently this is still wrong. What exactly am I not doing here?
But why would the problem say that it's going in a circle then? I'm really confused.
So would I need to do 2∏*(.28) / 2.1 seconds to get the velocity? If this is correct, then would I be able to plug it into the equation I set up for myself successfully?
So I should just scratch the "+ mg" I...
Homework Statement
A golf ball with mass m = 0.05 kg is tied to a massless string of length L = 0.28 m. The ball is made to swing in a circle such that the string is horizontal throughout the motion. The ball makes one revolution every t = 2.1 s.
m = 0.05 kg
L = 0.28 m
t = 2.1 s
