A 0.20 kg yo-yo consists of two solid disks of radius 7.30 cm joined together by a massless rod of radius 1.0 cm and a string wrapped around the rod. One end of the string is held fixed and is under constant tension T as the yo-yo is released.

(a) Find the acceleration of the yo-yo. (solved)
.35 m/s2

(b) Find the tension T. (unsolved)

Step 1

a)

Consider a yo-yo with 2 solid discs of mass 0.2kg each and radius 7.3cm connected through a  mass less rod of radius 1cm. Write the equation for moment of inertia of discs.

Step 2

Write the equation for torque and rearrange to get tension on the rod

Step 3

Write the equation for net...
