Question

A yoyo is consists of two disks each for radius .1m and mass .25kg attached by a massless .02m diameter axle. A .8m long string is wrapped around axle. The yoyo is released from rest and allowed to unwind down the string spinning faster and faster. What is the linear velocity of the yoyo when the string has unrolled its entire length?

b. When the yoyo reaches the end of the rope, it begins to travel upward again like a reverse yo-yo such that it requires the same amount of time for the mass to go up as it took to go down. What is the period of this oscillation? What is the frequency? What is the amplitude?
