1. During which time interval(s), if any, are there no forces acting upon the object? List all that apply.
2. During which time interval(s), if any, are the forces acting upon the object balanced? List all that apply.
3. During which time interval(s), if any, is there a net force acting upon the object? List all that apply.
4. During which time interval(s), if any, is the net force acting upon the object directed toward the right? List all that apply.
5. During which time interval(s), if any, is the net force acting upon the object directed toward the left? List all that apply.
