AP Physics Review (No Rotation or Osc)

Given the FBD, which of the following must be true?

• The frictional force must be accelerating the system to the left.

• The box must be accelerating to the right.

• The box must be moving to the right.

• The FBD is incorrectly drawn. This situation isn't possible

Which of the following is true about the system shown?

• The system is not accelerating.
• The tension between m₂ and m₁ is less than the tension between m₂ and m₃
