(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A bug of mass m is stuck to a point on the rim of a rolling wheel (of radius r)... which traces out a path called a cycloid. The position vector of the point (bug) is given by:

r(theta) = r(theta - sin(theta))i+ r(1 - cos(theta))j

For a wheel rolling with constant angular spped...

2. Relevant equations

A) Determine the velocity vector v = vxi+ vyj.

B) Determine the acceleration vector a =axi+ ayj

C) Verify the magnitude of the acceleration vector is given by a = r(greek w)^2

3. The attempt at a solution

The derivatives i took for each vector looked very incorrect.
