Choosing acceleration vector directions on a test

[november1992]

Homework Statement

This was a question on my test. I had to choose the direction of the acceleration vector for each position. I was wondering if I chose the correct answers.

Homework Equations

a = gsinθ

Ʃ$F_{y}$ = $N_{1S}$( normal force) - $W_{1E}$ ( weight force)

The Attempt at a Solution

for position one I picked 4
for position two I picked none (there was an option for that)
for position three i picked 3

The answers you gave look right to me.
