Hi, I'm new to this forum, and I must admit that I'm in dire straits when it comes to solving this problem. I have tried reading through the textbook for help but it isn't clear enough for my liking and my professor is unavailable at this time. So without further ado, here is the problem that's been plaguing me: A little girl is sitting on a playground swing. Her father pulls her to the right with just enough force to hold her stationary. If the little girl's weight is 35 pounds, what force is the father exerting? I cannot figure a way to draw the picture the problem gives on here, but it gives a further bit of information: The angle is 25 degrees to the vertical. It then asks me to draw the diagram (That much I figured out) and to do the calculations. I'm stumpted as to how exactly the formula works for a problem like this though, please help! Thanks in advance.
