Acockroach rides the rim of a rotating merry-go-round. if the angular speed of this system (merry-go-round cockroach) is constant, does the cockroach have (a) radial acceleration and (b) tangential acceleration? if v is decreasing, does the cockroach have (c) radial acceleration and (d) tangential acceleration?

when earth is in rotational motion around the sun,it displaces from its place.
