Two object each of mass 1.5 kg are moving in the same straight line but in opposite direction . The velocity of each object is 2.5 m/s before the collision during which they stick together. What will be the velocity of the combined object after collision.

Answer:
The combined velocity will be zero.
Explanation:
When two equal masses moving with equal but opposite velocities collides. Their velocities cancel each other and net velocity becomes zero.
This is in favor of the law of conservation of momentum

Answer:
0 is the final velocity of both the objects.
Explanation:
m1u1+m2u2=m1v1+m2v2 (conservation of momentum)
1.5x2.5 +1.5x-2.5 =1.5x v + 1.5x v
( the minus comes in the initial velocity of the second object because it is coming in the opposite direction...so u can take any value as plus or minus)
3.75-3.75=3v
0=3v
v=0/3=0
v=0
