question 108

Multiple Choice

Two experiments are performed. In (A) , an 18.0 N force pushes horizontally on a 2.00 kg block that then pushes on a 4.00 kg block. In (B) , an 18.0 N force pushes on a 4.00 kg block that then pushes on a 2.00 kg block. Which statement is correct?

• A) The acceleration is 3.00 m/s² in both (A) and (B).
• B) The acceleration is 4.50 m/s² in both (A) and (B).
• C) The acceleration is 6.00 m/s² in both (A) and (B).
• D) The acceleration is 9.00 m/s² in both (A) and (B).
• E) The 2.00 kg block has a 9.00 m/s² acceleration. The 4.00 kg block has a 4.50 m/s² acceleration.
