a merry go round wheel rotates with an angular speed of 2 rad/s. consider two children on the wheel, one standing .5 m and the other 1.5 m away from the center of the wheel. the chid at 1.5 m distance is moving__________ times faster than the child at .5 m distance.
what is the tangential speed of the child at 1.5 m?

Tangential speed = rω
Since ω (angular speed) is constant, so the tangential speed is proportional to the radius.
