Final answer:
The momentum of a car with a mass of 250 kg that travels 500 m in 25 seconds is 5000 kg · m/s.
Step-by-step explanation:
The momentum of an object is calculated using the formula momentum (p) = mass (m) × velocity (v). To find the momentum of a car that travels 500 m in 25 seconds with a mass of 250 kg, we first need to find the car's velocity. The velocity can be calculated using the formula velocity = distance / time. So, the velocity of the car is 500 m / 25 s = 20 m/s. With the velocity known, we can now calculate the momentum:
p = m × v
p = 250 kg × 20 m/s
p = 5000 kg · m/s
Therefore, the momentum of the car is 5000 kg · m/s.
