A force of 250 N is applied to an object that accelerates at a rate of 5 m/s². What is the mass of the object?

A. Divide the force by the acceleration, so the mass is 50 kg.
B. Multiply the force and acceleration, so the mass is 1250 kg.
C. Divide the acceleration by the force, so the mass is 0.02 kg.
D. Subtract the acceleration from the force, so the mass is 245 kg.

To determine the mass of an object when given the force and acceleration, apply Newton's Second Law (F=ma). In this scenario, the force is 250N and acceleration is 5 m/s². By dividing the force by the acceleration (250N / 5 m/s²), we find the mass is 50 kg.

Explanation:

The subject of this question is Physics and it's applicable for the High School grade. This problem can be solved using Newton's Second Law of motion, which states that Force equals mass times acceleration (F=ma). Therefore, to solve for mass, we must rearrange the equation to be m=F/a.

In this case, the force (F) being applied is 250 N and the acceleration (a) is 5 m/s². Applying these values to our equation we have: m = 250N / 5 m/s². This results in a mass (m) of 50 kg. So, the mass of the object in question is 50 kg.

As demonstrated by the above calculations, the correct answer to this problem is Option 1: Divide the force by the acceleration.
