Answer:
Fnet = 13920 Newtons
Explanation:
Net force can be defined as the vector sum of all the forces acting on a body or an object i.e the sum of all forces acting simultaneously on a body or an object.
Mathematically, net force is given by the formula;
[tex] Fnet = Fapp + Fg[/tex]
Where;
- Fapp is the applied force
- Fg is the force due to gravitation
Given the following data;
Mass, m = 800 kg
Acceleration, a = 7.6m/s²
To find the applied force;
[tex] Fapp = ma[/tex]
Substituting into the equation, we have;
[tex] Fapp = 800 * 7.6[/tex]
Fapp = 6080N
To find the gravitational force;
We know that acceleration due to gravity, g = 9.8m/s²
[tex] Fg = mg[/tex]
Substituting into the equation;
[tex] Fg = 800 * 9.8[/tex]
Fg = 7840N
To find the net force;
[tex] Fnet = Fapp + Fg[/tex]
Substituting into the equation, we have;
[tex] Fnet = 6080N + 7840N[/tex]
Fnet = 13920 Newton.
Therefore, the net force experienced is 13920 Newton.
