Block 1, with mass m1 and speed 5.0 m/s, slides along an x axis on a frictionless floor and then undergoes a one-dimensional elastic collision with stationary block 2, with mass m2 = 0.50m1. The two blocks then slide into a region with a coefficient of kinetic friction of 0.50 where they stop. How far into that region do the two blocks slide?
block 1 _____ m
block 2 _____ m
