Rotational and Linear

  1. Mar 29, 2004 #1
    Can someone help me set this up? Please?

    A 12 kg mass is attached to a cord that is wrapped around a wheel with a radius of 10 cm. The acceleration of the mass down the frictionless incline is measured to be 2 m/s^2. Assuming the axle of the wheel to be frictionless, determine: a) the force in the rope, b) the moment of inertia of the wheel, and c) the angular speed of the wheel 2 s after it begins rotating, starting from rest.

    I'll take any help that I can get, and I really appreciate anyone helping me out. Thank you.

    I'm pretty sure you might need the slope of the incline for this problem.

    I forgot to add that in the problem. There is a 37 degree incline.

    Do you have a picture? Is the mass sliding down the incline? Is the wheel the 12 kg mass?

    Rebel,

    Where are you having problems? Can you draw a FBD?
