1) Consider two boxes side by side, being pushed to the right. Box A, on the left, is 5 kg. Box B, on the right, is 3 kg. They are being pushed by a person using 30 Newtons of force. The broad goal is to understand everything, including their acceleration and their interaction forces. For now, treat friction as zero. a) Draw a motion diagram, label acceleration. Use the idea that the boxes have the same acceleration. b) Force list for Box A and for Box B. c) Free body diagram for Box A & B. Note which forces are caused by the same interaction. These must be the same length. d) Write each force as a vector using bracket notation. Use the idea that two of the forces must have the same length e) Write (sum of F) = m x a for each box f) Calculate the acceleration and the interaction forces between the boxes
