Transcribed Image Text:

Block 1, of mass m₁, moves across a frictionless surface with speed u;. It collides elastically with block 2, of mass m2, which is at rest (v; = 0). (Figure 1)After the collision, block 1 moves with speed us, while block 2 moves with speed uf. Assume that m₁ > m2, so that after the collision, the two objects move off in the direction of the first object before the collision.
