Use F = ma, where F is force (in newtons), m is mass (in kg) and a is acceleration (in m/s²).
In this case F = 50 N and a = 10 m/s², so we have the equation:
50 = 10m.
Now divide both sides by 10, getting:
m = 5 kg.
So the answer is C. 5.0kg
Taking into account the Newton's second law, the mass of the object is 5 kg.
Newton's second law, called the fundamental law or fundamental principle of dynamics, states that a body accelerates if a force is applied to it.
In other words, Newton's second law states that, to change the state of motion of an object, an external force must be applied.
Newton's second law defines the exact relationship between force and acceleration by stating that the accelerations a body experiences are proportional to the forces it receives.
That is, the acceleration of an object is directly proportional to the sum of all the forces acting on it and inversely proportional to the mass of the object.
Then, mathematically, Newton's second law is expressed as:
F= m×a
where:
In this case, you know:
Replacing:
50 N= m× 10 m/s²
Solving:
m= 50 N÷10 m/s²
m= 5 kg
Finally, the mass of the object is 5 kg.
