Two object, 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 ms^(-1)` before the collision during which they stick together. What will be the velocity of the combined object after collision?

Explanation

To solve the problem of two objects colliding and sticking together, we will use the principle of conservation of momentum. Here’s a step-by-step solution:

### Step 1: Identify the masses and velocities of the objects
- Mass of object 1, \( m_1 = 1.5 \, \text{kg} \)
- Velocity of object 1, \( v_1 = 2.5 \, \text{m/s} \) (let's assume this is in the positive direction)
- Mass of object 2, \( m_2 = 1.5 \, \text{kg} \)
- Velocity of object 2, \( v_2 = -2.5 \, \text{m/s} \) (since it is moving in the opposite direction)
