Cundider to boll collide with each other A and B than force on A F=dp/dt and force on 2nd boll is. dp•/dt• . Now add both the equation F¹+F² =dp¹/dt+dp²/dt.. now take 1/dt(p¹+p²)and by momentum cunservation p¹+p²=0 so F¹+F²=o and F²=-F¹ hence proved

F=ma and we know that if v is constant than than a= o so F = o and it verify newton 1st low no external force aplide on that body
