A block of mass 1.88 kg is placed on a frictionless floor and
initially pushed northward, whereupon it begins sliding with a
constant speed of 4.47 m/s. It eventually collides with a second,
stationary block, of mass 4.31 kg, head-on, and rebounds back to
the south. The collision is 100% elastic. What will be the speeds
of the 1.88-kg and 4.31-kg blocks, respectively, after this
collision?
1.) 0.88 m/s and 2.00 m/s
2.) 2.72 m/s and 1.75 m/s
3.) 2.62 m/s and 2.24 m/s
4.) 1.75 m/s and 2.72 m/s
