a boy and a girl pulling a box at the same time with 10n of force each. what is the net force acting on the object

Sagot :

it's been a while since i study this but i think the answer is either 0n or 20n
1.) If the forces are exerted in the same direction, then:
   10n + 10n = 20n to the direction of the forces
 The net force is 20n to the direction of the forces.

2.) If the forces are exerted on opposite directions, then:
   10n + -10n
 = 0
  There is no net force. The sum of all the forces is 0.
