Taking into account the Newton's second law, the correct answer is option D): the force the student applied to the box is 50 N
Newton's Second Law, also called the Fundamental Law of Dynamics, indicates that: "The change in motion is directly proportional to the printed motive force and occurs according to a straight line along which that force is printed." This means that the acceleration of a moving object depends on the amount of force applied to it at a given moment, in order to modify its trajectory or speed.
Mathematically, Newton's second law is expressed as:
F= m×a
where:
-
F = Force [N]
- m = Mass [kg]
- a = Acceleration [m/s²]
In this case, you know:
Replacing:
F= 10 kg× 5 m/s²
Solving:
F= 50 N
Finally, the correct answer is option D): the force the student applied to the box is 50 N
