Two blocks, with masses m1 = 2.5 kg and m2 = 14 kg , approach each other along a horizontal, frictionless track.The initial velocities of the blocks are v1 = 12.0 m/s to the right and v2 = 3.4 m/s to the left. The two blocks then collide and stick together. Which of the graphs in (Figure 1) could represent the force of block 1 on block 2 during the collision?
