Initials: Problem 1 - 25 points For gange - ABEDIaYHT Isband Vineet ham string central A yo-yo is made of two identical disks of seong cylinder mass M and radius R, glued together to a central cylinder of negligible mass and disks radius R/2. A side view and a top view are shown to the right. A string of negligible thickness is wound tightly around the central cylinder, so that the string does not R slip around it. The yo-yo is released from rest and drops vertically down, while R/ R/2 . . ... being held by the upper end of the string. The acceleration due to gravity has magnitude M g. M Side view Top view a- Determine the rotational inertia of the yo-yo with respect to its rotational axis of symmetry. ion nevis Tedlion sved I der tonot you no mate to Us yd bebids I ,noHibbs ulmsxe earli no bun havigoat "aveda bendmo es asiorlog motionimaxs art b- Write down the equations describing the rotational motion of the yo-yo about its rotational axis of symmetry and the translational motion of its center of mass.elfilial Initials: c- Determine the magnitude of the acceleration of the center of mass of the yo-yo as it unwinds downward. grub boviseron ei ylionsup lady alnest wow no trend boy bill to plies Isathov end of Now let's consider that the rod initially rotates in tow angular speed on You still throw the balthorizontally man wednesday a distance (/4 from the vertical axle, but thiis the the Union of the heatavelartest plea The normal to the rod (2-0).
