Explanation / Answer

Yes at the center of merry go round you will have the same angular velocity as of merry go round .

As at center r=0 then v= r.w =0

So linear velocity will be zero .

Now as linear velocity is zero there will be no linear kinetic energy .

Rotational kinetic energy is 1/2(Iw^2) . But as r =0 ( i.e distance from axis of rotation) moment of inertia will be zero . So rotational kinetic energy will also be zero .so you will not have energy at the center of merry go round
