Amerry-go-round is spinning at a rate of 4.04.0 revolutions per minute. cora is sitting 0.50.5 m from the center of the merry-go-round and cameron is sitting right on the edge, 2.0 m from the center. what is the relationship between the rotational speeds of the two children?

angular speed of both the children will be same

Explanation:

Rate of revolution of the merry go round is given as

f = 4.04 rev/min

so here we have

here we know that angular frequency is given as

now this is the angular speed of the disc and this speed will remain same for all points lying on the disc

Angular speed do not depends on the distance from the center but it will be same for all positions of the disc

since you're a real machine, your ama is always less than your ima, because you can never totally eliminate friction.
