Answer :
Final answer:
The acceleration of a 4kg object acted upon by a 28 Newton force can be calculated by dividing the force by the mass, which equals 7 m/s².
Explanation:
In Physics, the concept of acceleration is explained via Newton's second law of motion, which states that force equals mass times acceleration (F = ma). To find the acceleration, it's as simple as rearranging the equation into a = F/m. Let's now apply this rule in the context of the question.
A 28 Newton force is acting on a 4kg object. To calculate the acceleration, we divide the force (28N) by the mass of the object (4kg). Mathematically, 28N divided by 4kg equals to 7 m/s².
