126. The momentum before the collision (with + x rightward) is (. 6 0 kg)(8.0 m / s) (4.0 kg)(2.0 m / s) 56 kg m / s. += (a) The total momentum at this instant is ( . 6 0 kg)(6.4 m / s) (4.0 kg) + G v . Since this must equal the initial total momentum (56, using SI units), then we find 4.4 m/s. v = G (b) The initial kinetic energy was 1 2 60 40 kg)(8.0 m / s) 1
