Question: A parent holds a small child in a swing so that the angle of the swing support is at 20 degrees to the vertical. The child’s weight is 200N and the swing seat weighs 50N. What horizontal force must the parent apply?
The answer provided in the textbook is 72.8N, but I’ve been struggling to get the same answer as I’m rather confused by the wording of the question and so I can’t really picture how the situation in the question would look like. Thank you in advance.
