QUESTION 4 Spain" A block of mass 1.46 kg is placed on a frictionless floor and initially pushed northward, whereupon it begins sliding with a constant speed of 6.00 m/s. It eventually collides with a second, stationary block, of mass 3.49 kg, headon, and rebounds back to the south. The collision is 100% elastic. What will be the speeds of the 1.46-kg and 3.49-kg blocks, respectively, after this collision? 0.98 m/s and 2.73 m/s 2.46 m/s and 3.54 m/s 3.54 m/s and 2.46 m/s 2.06 m/s and 3.00 m/s 3: \"Ail
