Final answer:
The momentum of a car with a mass of 900 kg traveling north at 27 m/s is 24300 kg·m/s.
Step-by-step explanation:
The momentum of an object can be calculated using the formula P = m x v, where P represents momentum, m represents mass, and v represents velocity.
In this case, the car has a mass of 900 kg and is traveling north at 27 m/s. Using the formula, we can calculate its momentum as:
P = 900 kg x 27 m/s = 24300 kg·m/s
Therefore, the momentum of the car is 24300 kg·m/s, which means that the car has a significant amount of momentum due to its mass and velocity.
