Answer» tion:let there be two masses M1 and m2 velocity of m1-u1 m2-u2after COLLISION v1 and v2momentum before collision=m1u1+m2u2 momentum after collision =m1v1+m2v2by newton 3RD law of motion,f1=-f2 during collision m1(v1-u1)/t = -m2(v2-u2)/tm1v1-m1u1 =m2u2-m2v2by transposition m1u1+m2u2=m1v1+m2v2 |
