For my assignment I have to write a report on the mechanics of an electric generator. I need to reference for physics textbooks. Anyone able to recommend some texts books that may be able to help me with this?

For the purpose of this thread I did change the equation a bit from the my homework as a result I got decimal numbers which may seem a bit strange. S I got 250.28 and X i got 26.25

Hey I ended up working it out. Took me a good few hours but yes I ended up with a quadratic. Thanks for the help. :)

Am really sorry ill keep all that in mind. I seriously have no idea where to go with this. I've tried the method of elimination/substitution. Does this perhaps have to be a quadratic function?

6570/x+9 6570/19 = 324.73

Should i divide both sides by XS? I know i need to isolate one of the terms. Just not sure how to go about it.

What do you mean by write S in terms of X?

Am a little stuck on a question in my maths homework. Here goes. $6570 to be divided among members of a family. 9 other members of the family find out about the cash and insist on there share. as a result the share was reduced by $120. Find original number of family members. So...

In need of help. Ill write it is how it is in the textbook. Find the equation of the line having gradient 3/4, that passes through 7,11. Express your answer in the form i) ax + by + c =0 and ii) y = mx + c As one point and the gradient are known, use the formula: y - y1 = m(x-x1)...

ahh got it. Thanks for the help. Turns out I drew the triangle upside down so of course I was never going to get the degrees correct. :)

Worked out the speed 26 m/s Answer sheet tells me 67 degrees 23 min west of north? How does it arrive at that??

This is problem very basic for all of you but I am struggling to grasp this. Heres the problem A cricketer is running due north with a cricket ball at 10 m/s and throws the ball due west at 24 m/s. Find the direction of the ball and its speed. Please give me a details explanation as...
