Two Experiments Are Performed

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.
