Final answer:
To calculate the force required to accelerate a 150 kg object at 20 m/s², we use Newton's second law (F = m × a). The result is a force of 3000 N, which is answer choice A.
Step-by-step explanation:
The question involves calculating the force needed to produce an acceleration for a given mass, which is a fundamental concept in physics. To find the force required, we use Newton's second law of motion, which states that force is equal to mass times acceleration (F = m × a).
In this case, the mass (m) of the object is 150 kg and the acceleration (a) is 20 m/s². Hence, the force (F) can be calculated as follows:
F = m × a
F = 150 kg × 20 m/s²
F = 3000 N
Therefore, the force needed to produce this acceleration is 3000 N, which corresponds to answer choice A.
