Tangential component of linear acceleration of point on flywheel

  1. Apr 2, 2008 #1
    What is the magnitude of the tangential component of the linear acceleration of a particle that is located at a distance of 50 cm from the axis of rotation when the flywheel is turning at 78.0 rev/min?

    I took 78 rev/min and converted it to rad/s and got 4.08 rad/s. I then multiplied that by .5m to get my answer. Am I doing this right?

    Second part: What is the magnitude of the net linear acceleration of the particle in the above question?

    I don't know how I should solve this problem.

    You're calculating velocity. The question is asking for acceleration.
