4.A block of mass 1.98 kg is placed on a frictionless floor and initially pushednorthward, whereupon it begins sliding with a constant speed of 5.07 m/s. Iteventually collides with a second, stationary block, of mass 3.24 kg, head-on and rebounds back to the south. The collision is 100% elastic. What willbe the speeds of the 1.98-kg and 3.24-kg blocks, respectively, after thiscollision?0.61 m/s and 1.88 m/s1.22 m/s and 3.85 m/s3.85 m/s and 1.22 m/s2.46 m/s and 2.54 m/s
