To calculate the mass of the car, we can use Newton's second law of motion, which states that force (F) is equal to the mass (m) multiplied by acceleration (a):
F = m * a
In this case, the car is running at a constant velocity of 12 m/s, which means its acceleration is zero (since acceleration is the rate of change of velocity). Therefore, we can rewrite the equation as:
F = m * 0
Since any number multiplied by zero is zero, the equation simplifies to:
F = 0
However, you mentioned that the force of the car is given as 1000 N. This value contradicts the information that the car is running at a constant velocity, as there should be no net force acting on the car to maintain a constant velocity. Therefore, the given force value of 1000 N seems inconsistent with the scenario of a car running at a constant velocity of 12 m/s.
If there is additional information or clarification regarding the force acting on the car, please provide it so that a more accurate calculation can be made.
