Final answer:
Using Newton's second law, the acceleration of a car with a mass of 1000 kg pushed by a 2000 N force is calculated to be 2 m/s², which is option a).
Step-by-step explanation:
A car with a mass of 1000 kg is at rest at a stoplight. When the light turns green, it is pushed by a net force of 2000 N for 10 s. To find the value of the acceleration that the car experiences, we use Newton's second law of motion, which states that the force applied to an object equals the mass of the object times its acceleration (F = ma).
In this case, we have:
- Force (F) = 2000 N
- Mass (m) = 1000 kg
By rearranging the formula to solve for acceleration (a), we get:
a = F / m = 2000 N / 1000 kg
Therefore, the acceleration (a) is:
a = 2 m/s²
So the correct answer is a) 2 m / s².
