Question

A 1200 kg automobile is traveling at a speed of 20 m/s when it collides with a truck at rest with a mass of 10,000 kg. What is the momentum of the vehicle before the collision?

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 automobile before the collision is found by multiplying its mass (1200 kg) by its velocity (20 m/s), resulting in 24000 kg·m/s.

Step-by-step explanation:

The momentum of a vehicle before a collision is calculated by multiplying its mass by its velocity. Given that the mass of the automobile is 1200 kg and the speed is 20 m/s, the momentum p can be found using the equation p = mv, where m is the mass and v is the velocity.

The momentum of the automobile before the collision is therefore:

p = 1200 kg × 20 m/s = 24000 kg·m/s.

The correct answer is b) 24,000 kg(m/s).
