**i-clicker Question**

The hockey players just sat down but the log hasn’t started moving yet. What is the direction of the angular acceleration, α, of the log?

A) ↓  
B) ←  
C) ⊗  
D) ⊙  
E) No direction since the log isn’t moving

**Diagram Explanation:**

In the diagram, two hockey players are sitting on a log placed over a light blue surface. There are downward arrows beneath the players indicating the forces acting on the log. The center of the log is marked with a symbol resembling concentric circles, possibly indicating the point of rotation or balance.
