This question is a long free-response question. Show work for each part. Physics students are studying linear and simple harmonic motion. They place two identical blocks on a horizontal, frictionless surface. On the opposite end of the surface from the blocks is a horizontal, uncompressed, ideal spring with negligible mass and a spring constant k₁ connected to a vertical wall. The figure below shows scenario 1 and four stages of the experiment at specific time intervals: t₁ through t₄. Scenario 1
