Re: Calculus 135 @ Rutgers University... Please HELP!

That's a lovely algebra problem. Where's the Calculus?

"at the central axis" means r = 0

"midway" means r = R/2

Plug'n'chug.

I really stink at word problems. Do you have any tricks to solve these problems better?

If you just told me to do so flat out I would obviously know how to do this!

How embarrassing :(

Thank you.

Thank you.

Interpret the questions in terms of the notation given, if no notation given invent some.

TKH has already told you:

For (a) r=0

For (b) r=R/2

Now you just plug the given information into the right hand side of the formula for speed.
