Final answer:
The net force required to accelerate a 20.0 kg object to 10.0 m/s² is 200 N.
Step-by-step explanation:
The net force required to accelerate an object can be calculated using Newton's second law of motion, which states that force equals mass times acceleration (F = ma). In this case, the mass of the object is 20.0 kg and the acceleration is 10.0 m/s². Therefore, the net force required can be calculated as:
F = ma = (20.0 kg)(10.0 m/s²) = 200 N
The force needed is directly proportional to the mass and acceleration, and in this scenario, it requires 200 N of force to achieve the given acceleration on a 20.0 kg object.
So, the correct answer is option a) 200 N.
