Answer:
ANSWER IS ZERO
Explanation:
GIVEN : two objects of same mass are moving in opposite direction along the same line .
And to find the combined velocity
collision must be inelastic .
When both particles combined then mass of new particle will be 3 kg .
In inelastic collision we can apply conservation of momentum
so
m1v1 + m2v2 = ( m1+ m2 ) v
where v is combined velocity ,
and it is given that m1= m2 and v1 = v2 and are in opposite direction
so equation will be
m1v1 - m2v2 = ( m1 + m2 ) v
as ,m1v1 = m2v2
0 = ( m1 + m2 ) v
therefore , v = 0
