Q. An adult exerts a horizontal force on a sewing that is suspended by a rope of length L, holding it at an angle x with the vertical. The child in the swing has a weight W and dimensions that are negligible compared to L. the weight of the rope and of the seat are negligible. In terms of W and X, establish

a) tension in the rope
b) horizontal force exerted by the adult.
The adult releases the swing from res. in terms of W and X determine
