Question

Girl pulls the heavy crate ehute 10 units force in the same direction as the girl. What will be the net force that will act on object? Will the object move​

Answer 1

Answer:

The net force force acting on the crate depends on the direction of the two forces and the amount of friction acting on the crate. The resultant vector is the vector sum of the 3 forces involved.

If the boy and the girl are acting in the same direction, their combined forces is 20 newtons. If the force of friction is 8 newtons opposing their combined forces then the net force acting on the object is (20 N - 8 N) which can be simply written as 12 N in the direction of their combined forces.

If the 3 forces are not in the same line then use trigonometry to determine the net force.
