Hello friend

Here is your answer!!
In the question..
Given:
The mass of first object (m1) = 100g = 0.1kg.
The mass of the second object (m2) = 200g = 0.2kg.
Initial velocity of first object (u1) = 2m/s.
Initial velocity of Second object (u2) = 1m/s
Final velocity of the first object= 1.67m/s.
We have to find the, final velocity of the second object,
means,(u2) = ??.
By using the formula,
m1u1 + m2u2 = m1v1 + m2v2
(0.1 x 2) + (0.2 x 1) = ( 0.1 x 1.67) +(0.2 x v2)
(0.2) + (0.2) = (0.167) + (0.2v2)
0.4 = 0.167 + 0.2v2
0.2v2 = 0.167 - 0.4
0.2v2 = 0.233
v2 = 0.233/0.2
v2 = 1.165 m/s.
Therefore the final velocity of the second object is 1.165 m/s.
I hope this will helps you.
Thanks.
