Document Summary

When fnet, external = 0, then dptotal/dt = 0. When fnet, external 0, then dptoal/dt 0. Dptotal/ dt = fnet, external = 0. When mass 1 and mass 2 are on a frictionless floor vinitial, 1= 3m/s and vinitial, 2= 0m/s. M1 is moving at a constant velocity toward m2, then once m1 hits m1 and m2 move together as a system. Ptotal, x = pinital, x = pfinal, x. These two above are part of inelastic collisions. K1, after + k2, after = (k1 + k2)(m1/m1+m2) Details of the internal forces during the collision influence the amount of energy lost. But if fnet, external = 0, ptotal is not conserved.
