Final answer:
The momentum of a 1.60 x 10^3 kg car traveling at 20.0 m/s is 32,000 kg·m/s, calculated using the momentum formula: mass x velocity.
Step-by-step explanation:
To calculate the momentum of a car, you can use the formula: momentum = mass × velocity, where mass is in kilograms and velocity is in meters per second.
For a car with a mass of 1.60 x 103 kg traveling at 20.0 m/s, the momentum would be calculated as follows:
momentum = (1.60 x 103 kg) × (20.0 m/s) = 3.20 x 104 kg·m/s.
The car's momentum is therefore 32,000 kg·m/s when it is traveling at 20.0 m/s.
