The force applied on an object is calculated using the formula , where is the acceleration of the object (measured in meters per second squared, or m/s2), and is its mass (measured in kilograms, or kg). The force is then measured in newtons. Which of the following is the expression of newtons in terms of the base units kilograms, meters, and seconds?
