According to the definition of the force, It is defined as the multiplication of the mass and acceleration (or, the rate change of the quantity of motion)
[tex]F=ma[/tex]
where:
- F: is the force in Newtons (N)
- m: is the mass in kilograms (Kg)
- a: is the acceleration in [tex]m/s^{2}[/tex]
Then, in our problem
[tex]F=ma= 500 * 15=7500 N[/tex]
