Question

In the previous question, if the automobile and the truck stick together after the collision, what is the momentum of the combined mass?

a) 60 kg(m/s)
b) 24,000 kg(m/s)
c) 34,000 kg(m/s)
d) 200,000 kg(m/s)

Answer 1

The momentum of the combined mass, if the automobile and the truck stick together after the collision, is b) 24,000 kg(m/s).

Step-by-step explanation:

When two objects stick together after a collision, the law of conservation of momentum applies. The total momentum before the collision is equal to the total momentum after the collision. If the automobile and the truck stick together, their combined mass is 4,000 kg (2,000 kg + 2,000 kg), and their combined velocity is the same as the velocity of the truck before the collision, which is 6 m/s.

The momentum (p) is calculated as mass (m) multiplied by velocity (v). Therefore, the momentum of the combined mass is 4,000 kg * 6 m/s = 24,000 kg(m/s).

Option B is correct
