Yea I noticed the error, I'm working on fixing it now. Can you elaborate more on how to find the radius? I'm not very good at this stuff..

http://gyazo.com/bc7f6da4d4c4aca300bb5efb2410fc8d.png The problem, and my solution are in the image. I need help on finding the equation of the osculating circle, I found radius but I don't know where to go from there. Also if you could just check if my math seems correct that would help me...

Question link: http://gyazo.com/4d52ab2521e5b222241718ea1b7ccb08.png I have to solve this using vectors, not geometry My professor said the equation that's required is -v* = 2 proj v onto n - v and v* is reflected vector, so I don't really understand how to do this First off I don't...

I think so, so let's say the minute hand at 6pm is r1 and 10 is r2, so I think v1 would be the vector tangent to r1 would be vi, and vector tangent to r2 is vf. So I believe v1 would be -20x2pi/1200 cm/s= -0.105 cm/s. I'm not sure about v2 though.

I have to calculate it, which is what is confusing me...

A clock has a 20cm minute hand. From the 6PM mark to the 10PM mark, for the tip of the minute hand, calculate: a) the displacement vector in unit-vector notation b) the average velocity vector in unit-vector notation c) the average acceleration vector in unit-vector notation d) calculate the...
