Final answer:
The mass of the car is calculated by dividing its momentum by its constant speed. Using the formula m = p / v with the provided values, the mass of the car is found to be 1200 kg.
Step-by-step explanation:
The student asked: A car travels at a constant speed of 24 m/s and has a momentum of 28800 kg·m/s. What is the mass of the car?
To solve this problem, we need to use the formula for momentum, which is p = mv, where p is momentum, m is mass, and v is velocity. Given the momentum (p) is 28800 kg·m/s and the velocity (v) is 24 m/s, we can rearrange the formula to solve for mass (m): m = p / v.
Plugging in the given values:
m = 28800 kg·m/s / 24 m/s = 1200 kg
Therefore, the correct answer is A) 1200 kg.
