Help with this physics problem please?

It's hard to understand this stuff without drawing a picture. Draw a picture of a tree and a car and a rope, woman in the middle, rope deflected by 15 degrees.

Now we hope it''s obvious that if the woman weighs 115 pounds then the rope has to apply an upward force of 115 pounds. Next we remember Chief SohCahToa:

Sine = Opposite/Hypotenuse

Cosine = Adjacent/Hypotenuse

Tangent = Opposite/Adjacent

So the force in the rope is a vector corresponding to the hypotenuse of the triangle and the upward force of 115 lbs involves the sine of the angle. Everything after that is just simple arithmetic.

Get a ruler in your hands. Measure things until you start to understand how a ruler works. Measure some stuff and figure out where the center is. Say you measure a book and it's 7/8" thick. You look at your ruler and see that every eighth is divided into two sixteenths, so obviously half of 7/8" is going to be 7/16". If you write that out you have 1/2 x 7/8 = 7/16. And you notice that 1/2 is divided into 2/4 and then into 4/8 and so on, so you can convert anything to anything by multiplying all the numbers on top and then all the numbers on bottom.

Other rulers are divided into 10 and 100 parts. But an inch is still and inch, so anything on one ruler can be translated to the other ruler. A half inch on one ruler is 5/10 or 50/100 on the other. An eighth inch is just 12.5 marks when you have 100 marks per inch. A metric ruler divides an inch into 25.4 parts, so a half inch would be 12.7 of those parts. Pretty simple, isn't it? Practice this a bit and people will think you went to wizard school.

the galaxies rotate at speeds inconsistent with their obvious mass is since we do see it all. I am relating to it as being the theoretical Dark Matter. There are very powerful proofs that shows that darkish subject exist. One the is the inconsistent pace of and obvious mass. darkish subject makes up approximately seventy five% to eighty% of the problem within the Universe...

I need to know what type of tree...what type of rope...what type car....
