Great thank you so much for all your help. :0)

I am trying to find the force the torque exerts on the object The formula I used was Torque = R x F.

I decided to try T=R x F. What I got was that the torque of the wheel is equal to the radius times the unknown F times the sin90. .00016=.0025F F=.064N Does this look right to you?

Torque = R xF or Torque = I alpha or Torque = dL/dt. I understand that these are the formulas for torque, I am just not sure which one I am supposed to use.

ok so now that i know torque of the wheel is .00016kgm^2 and angular acceleration is 1.05 rad/sec^2. How do i figure out what the force is that the torque of the wheel is producing on a fixed object, say someone's head for example?

yes, your formula for acceleration is the one i meant. I understand that dw/dt is angular acceleration, so do i just not multiply by the radius? I am very confused here.

wouldn't the dw in this case just be the 10.5 rad/sec divided by 10(then number of seconds it takes for the wheel to stop?
