Look at the image, here :
The rope hangs from the point (0,4)..the bottom of the rope is at (0,1).....it swings out at a 60 degree angle (pi/3) from a vertical position in each direction....so....it reaches a height of 2.5 m as shown
We can use this to find the height :
[1 + 3*sin (30°) ] m = [1 + 3 (1/2)] m = [ 1 + 3/2 ] m = [1 + 1.5 ] m = 2.5 m
Hi Julius and all others,
When you ask a question please include the whole question.
I assume this question refers to an earlier thread - you should have asked your question with another post on the initial thread and then if you wanted to draw attention to it you could have made a new post just giving the link and saying that you have asked for more discussion/help.
