light string wrapped around a reel of radius $R=0.250\U{m}$ and mass
$M=3.00\U{kg}$. The reel is a solid disk, free to rotate in a
vertical plane about the horiizontal axis passing through its center

+as shown in Figure~P10.51. The suspended object is released from rest
$6.00\U{m}$ above the floor. Determine \Part{a} the tension in the
string, \Part{b} the acceleration of the object, and \Part{c} the
speed with which the object hits the floor. \Part{d} Verify your
