Answer : The force will be 4501.9
We can see that, two forces acting on the dummy in two different direction.
We know that, here two forces are given in perpendicular direction with each other.
We know the force is the vector addition law so, we will use the Pythagoras theorem for the resultant of the vectors
Now, the net force is

Two forces is given,


Now, the net force is



Hence, the force will 4501.9 N
If im correct the answer is gravity
and wind resistance if you lift it fast
