Question

a young man acquires a summer job at a local daycare center when they were pushing the Merry-Go-Round for some children he notices that the faster he makes the Merry-Go-Round go the happier the kids seem to be.so not being the sharpest knife in the drawer he begins to swing the Merry-Go-Round faster and faster until kids begin to fly off a witness describes the scene to the daycare centers supervise claims that the boy made the Merry-Go-Round goes so fast that the kids were forced off into the hay bales where they were unhurt do you agree with the witness account would you say that the kids were forced off the ride defend your response

Answer 1

As the man rotates marry go round , the kids experience an outward force , known as Centrifugal force.

This force depends on the mass of kids, speed of rotation and distance from the center . more massive kids , more will be the force and greater the force , speed of rotation will be greater and hence distance from the center will also be greater .

It is important to note that , centrifugal force does not actually exist , we feel it because we are in non inertial coordinates system.

In order to stay on circular patch, we must exert a force towards the center called centripetal force.

We know that marry go round is harder to stay on, the faster it rotates .

Hence speed of rotation should be proportional to the weight of kids .

F_c = mr².
