Part 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?
Part 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?
