Question

Derive newtons third law of motion sth yjr help of conservation of momentum

Answer 1

By the formula

Force = Mass × Acceleration

Acceleration=final velocity-initial velocity/time

F1= M1×v1-u1/t = m1v1-m1u1

F2= M2×v2-u2/t = m2v2-m2u2

F1=F2

By cancelling t from both the sides,

m1v1-m1u1 = m2v2-m2u2

m1u1+m2u2=m1v1+m2v2
