Answer:
90N
Step-by-step explanation:
The total resultant force acting on the desk being pushed by Sara and Carlo is 90N
A resultant force is a singular force that will act the same effect as the forces acting on a body.
- When two or more forces acts on a body in the same direction, their resultant is the sum of the individual forces.
- If it is in the opposite direction, the differences is the resultant force.
- The body will move in the direction of the applied force with a higher magnitude
So;
Resultant force = Force applied by Sara + Force applied by Carlo
Resultant force = 50N + 40N = 90N
