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 4.56 m/s. It eventually collides with a second, stationary block, of mass 4.89 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 4.89-kg blocks, respectively, after this collision? A 2.47 m/s and 2.28 m/s B 1.13 m/s and 2.27 m/s C 2.26 m/s and 2.30 m/s D 2.30 m/s and 2.26 m/s
