Final answer:
The acceleration of an object under a force can be calculated with Newton's second law, a = F/m. However, the given problem lacks sufficient details to provide an exact answer.This value is not within the provided option.
Step-by-step explanation:
To determine the acceleration of an object when a force is applied, you can use Newton's second law of motion, which states that the acceleration (a) of an object is directly proportional to the net force (F) acting on it and inversely proportional to its mass (m), expressed in the equation a = F/m.
In this scenario, if '1000 N attached to 2500 N' refers to two objects being pulled by a combined force of 4500 N, you would add the two masses to find the total mass: 1000 N/g + 2500 N/g, where g is the acceleration due to gravity (9.8 m/s²). However, without knowing the acceleration due to gravity or any other forces acting on the objects (like friction), we can't accurately calculate the mass or the acceleration. Assuming standard Earth gravity and ignoring other forces, the masses would be approximately 102 kg and 255 kg, respectively (since 1 N = 1 kg·m/s²). The total mass would then be 102 kg + 255 kg = 357 kg. Using the formula a = F/m, the acceleration would be 4500 N / 357 kg, which equals to approximately 12.61 m/s². This value is not within the provided options, suggesting there may be an error or misinterpretation in the question. For a more precise answer, additional details are required.
