Physics... rotation

posted by on .

A constant force of 40 N is applied tangentially to the rim of a wheel with 20 cm radius.
The wheel has a moment of inertia of 30 kg m2.

Show that the angular acceleration of
the wheel is 0.27 rad s-2

  • Physics... rotation - ,

    Torque=I*alpha
    force*radius=I(alpha

    solve for alpha.

  • Physics... rotation - ,

    oo...i totally forgot to expand torque to be the force x perpend. radius

    thanks..got it
