Question

If a car with a mass of 15,000 kgs. traveled 125 meters with a net force of 30,000 Newtons, what was the acceleration of the car?

A) 2 m/s².
B) 4 m/s².
C) 0.5 m/s².
D) 6 m/s².

Answer 1

The acceleration of the car is found by dividing the net force (30,000 N) by the mass of the car (15,000 kg), which results in an acceleration of 2 m/s².

Step-by-step explanation:

To determine the acceleration of the car, we will use Newton's second law of motion, which states that the net force acting on an object is equal to the mass of the object multiplied by its acceleration (F = ma). So to find the acceleration (a), you divide the net force (F) by the mass (m).

Using the question's data:

• Net force, F = 30,000 N
• Mass of the car, m = 15,000 kg

Acceleration, a = F/m = 30,000 N / 15,000 kg = 2 m/s². Hence, the correct answer is A) 2 m/s².
