Answer :
The horizontal force that the seat must be pulled so that the ropes form an angle of 35o with respect to the vertical is 345.2 N.
Horizontal force to be applied
The horizontal force that the seat must be pulled so that the ropes form an angle of 35o with respect to the vertical is calculated as;
F = Wcosθ
where;
- W is weight of the child
- θ is angle of inclination of the rope
F = (43 x 9.8) x cos(35)
F = 345.2 N
