**Problem:**See

__NOTE__: The reference to weight "D" in the second line is incorrect.

**My Attempt:**

*Step 1:*Since this is a constant acceleration situation, I calculated the angular acceleration = 3 cm * -4 cm/s/s

*Step 2:*Employed the constant acceleration equation [tex] \omega^2 = \omega_0^2 + 2*\alpha*\theta [/tex] to obtain [tex]\theta = 3/2 [/tex]

*Step 3:*Lastly, I converted angle to length for the disc of radius 3 cm to obtain the required answer as 14.13 cm.

**Question:**This approach does not yield. What should I relook?

Look forward to your suggestion.wirefree
