Question

TWO INSECT

moving
of
are
toward each other the mass of
insect are 8m and m
& speed v and 4v the calculate
VELOCITY
of
centre of mass​

Answer 1

Velocity of centre of mass is =(m1v1+m2v2)/(m1+m2)
=(8m*v+m*4v)/(8m+m)
=12mv/9m
=4V/3

Answer 2

Answer:

Explanation:

linear momentum of P = mv

linear momentum of Q = (4m)(4v) = 16mv

ratio of momentum = mv/16mv = 1/16

ratio of momentum of P and Q = 1 : 16
