Homework Help: Bug physics.

  1. Jul 12, 2007 #1
    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.
