A body of mass 5 kg moving with a velocity 3 m/s
collides with another body of mass 3 kg at rest. After
collision, both move with the same velocity. Find
their common velocity.

3 m/ s is the right answer because of conservation of momentum

mass of body 1 = 5kg
initial velocity (u) = 3 m/s
final velocity (v) = v
mass of body 2 = 3kg
initial velocity (u) = 0 (at rest)
final velocity (v) = v
m1 u1 + m2 u2 = m1 v1 + m2 v2
5×3 + 3×0 = 5×v + 3×v
15+0 = 8v
v = 15/8
v = 1.88 m/s
