Final answer:
To find the mass of a car with a momentum of 24,000 kgm/s traveling at 20 m/s, use the formula m = p/v, which gives a mass of 1200 kg.
Step-by-step explanation:
The momentum of a car is defined as the product of its mass and velocity. Given that a car has a momentum of 24,000 kg∙m/s and a velocity of 20 m/s, we can calculate its mass by rearranging the formula for momentum (p = mv), which gives us m = p/v. Substituting the given values into the equation, we get:
m = 24000 kg∙m/s ÷ 20 m/s
m = 1200 kg
Therefore, the car's mass is 1200 kilograms.
