PLEASE SOME ANSWER THIS ASAP AND SHOW ALL THE WORK PLS A merry-go-round in a playground (spinning horizontal disk) of mass M and radius R is initially rotating inthe x/y plane at a constantω0around a fixed vertical axis through the middle of the disk. A girl of mass m runstowards italong a path that is tangent to the rim and then jumps on the rim and holds on. The disk spinsfasterafter she jumps on. Treat the girl as a point mass.a) Choose one: Which of the following is conserved for the disk+girl system before and after she jumps on?

Two identical balls, A and B, are each attached to very lightstring, and each string is wrapped around the rim of a pulley of mass Mon a frictionless axle. The only difference is that the pulley for ball Ais a solid disk, while the one for ball B is a hollow disk. If both balls are released from rest and fall the same distance,which one will have more kinetic energy, or will they have the samekinetic energy? Explain your reasoning.
