Physics... rotation
posted by Kimora 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 s2

Torque=I*alpha
force*radius=I(alpha
solve for alpha. 
oo...i totally forgot to expand torque to be the force x perpend. radius
thanks..got it
