- 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? (i) mechanical energy, ii) angular momentum, iii) linear momentum. iv) 2 or more of the above. b) Draw an overhead sketch of the disk with the disk rotating such that ω0 is in the +z direction (out). Show thevelocity vector of thegirl right before she jumps on. Solve for the necessary speed v that she must have in order for the disk to tripleits angular velocity after she jumps on. Your expression should depend on ω0, m, M, andR. Simplify it as much as…(II) A uniform horizontal rod of mass M and length l rotates with angular velocity w about a vertical axis through its center. Attached to each end of the rod is a small mass m. Determine the angular momentum of the system about the axis.
