☃️ Mass of the object = 1 kg
☃️ Velocity of the object before collision = 10 m/s
☃️ Mass of the stationary wooden block = 5 kg
☃️ Velocity of the wooden block before collision = 0 m/s
✴️ Total momentum before collision,
⚡ It is given that after collision, the object and the wooden block stick together .
- Total mass of the combined system =
- Velocity of the combined object = v
✨ According to the law of conservation of momentum,
✔️ Total momentum before collision = Total momentum after collision
__________________________
⭐ The total momentum after collision is 10 kg.m/s .
⭐ Total momentum just before the impact is 10 kg.m/s .
⭐ Total momentum just after the impact = = 6 × = 10 kg.m/s .
⭐ Therefore, velocity of the combined object after collision is .
