Final answer:
Without the specified forces applied to the car, we cannot calculate the car's acceleration; however, if the net force were given (e.g., 250 N), we could use Newton's second law to find that the acceleration would be 2.5 m/s² for a 100 kg car.
So, the correct answer is B.
Step-by-step explanation:
To determine the acceleration of a car with a mass of 100 kg given the applied forces, we use Newton's second law of motion, which states that the force applied on an object is equal to the mass of the object multiplied by its acceleration (F = ma).
Since the forces applied to the car are not specified in the question, we cannot calculate the exact acceleration without this information. However, if we had the net force applied to the car, we could find the acceleration by rearranging the formula to a = F/m, where 'a' is acceleration, 'F' is the net force, and 'm' is the mass of the car.
Here is an example, assuming a net force of 250 N is applied to the car:
The acceleration 'a' would be calculated as a = F/m = 250 N / 100 kg = 2.5 m/s² (Option B).
