    Center of mass using Mach's restatement of Newtonian Mechanics

    the first derivative to big R relative to t (dR/dt) in left hand side will give u already m1u1+m2u2 in right hand side then then multiply two side by dt and then make integrations two side u will get what u need

    Center of mass using Mach's restatement of Newtonian Mechanics

    derive R relative to t and then at t=0 R=R0 and m1u1+m2u2=constant
