Question

prove that when two bodies of masses m1 and m2 travelling in Opposite direction Collide each other two linear moment is conserved.​

Answer 1

Answer:

Here, m1=m2,u1=v,u2=−v

∴v1=(m1−m2)u1+2m2u2(m1+m2)

=(m−m)u1+2m(−v)2m=−v

and v2=(m2−m1)u2+2m1u1m1+m2

=(m−m)(−v)+2mv2m=v

Hence after collision, the two ball bearings will move with same speed, but their directios of motion are reversed.

mark as brainlyiest plz and thank me
