A block of mass 1.65 kg is placed on a frictionless floor and initially pushed northward, whereupon it begins sliding with a constant speed of 5.69 m/s. It eventually collides with a second, stationary block, of mass 3.85 kg, head-on, and rebounds back to the south. The collision is 100% elastic. What will be the speeds of the 1.65-kg and 3.85-kg blocks, respectively, after this collision? 1.82 m/s and 2.57 m/s 2.28 m/s and 3.41 m/s 3.41 m/s and 2.28 m/s 2.31 m/s and 2.85 m/s

Same situation as before. This time it s a block of mass 1.07 kg sliding with a constant velocity of 3.51 m/s to the north, which collides 100% elastically with a second, stationary block, of mass 4.28 kg, head-on, and rebounds back to the south, eventually colliding 100% elastically with a wall and rebounding northward.
