1. Homework Statement [/b]
Block 1, with mass m1 and speed 3.6 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 = 0.69m1. The two blocks then slide into a region where the coefficient of kinetic friction is 0.39; there they stop. How far into that region do (a) block 1 and (b) block 2 slide?
I used the elastic collision formula and got v1f= .6604m/s and v2f=4.260 m/s
can i use conservation of ke?? to find mass?
