Two objects, each of mass

$1.5\ kg$ , are moving in the same straight line but in opposite directions. The velocity of each object is

$2.5\ m\ s^{-1}$ before the collision during which they stick together. What will be the velocity of the combined object after collision?

Let us consider,

$m_1$ be the mass of first object

$m_2$ be the mass of second object

$v_1$ be the velocity of first object before collision

$v_2$ be the velocity of the second object before collision

$v$ be the Velocity of the combined object after the collision

From the law of conservation of momentum, We know that,

Velocity of the combined object after the collision $=$

$m\ s^{-1}$
