Final answer:
According to Newton's second law, the force (F = m * a) needed to accelerate a 1.875 kg object at a rate of 1.5 m/s² is 2.813 N, corresponding to option C.
Step-by-step explanation:
The question is related to the laws of motion and how to calculate the force required to accelerate an object. According to Newton's second law, the force applied to an object is equal to the mass of the object multiplied by its acceleration, which can be represented by the equation F = m * a. In this case, the mass (m) of the object is 1.875 kg and the acceleration (a) is 1.5 m/s². To find the force we multiply the mass by the acceleration:
F = m * a = 1.875 kg * 1.5 m/s² = 2.813 N
Therefore, 2.813 newtons of force are needed to accelerate a 1.875 kg object at a rate of 1.5 m/s², which corresponds to option C.
