A 50.0-kg child stands at the rim of a merry-go-round of radius 2.00 m, rotating with an angular speed of 3.00 rad/s.

  1. What is the child’s centripetal acceleration?
  2. What is the minimum force between her feet and the floor of the carousel that is required to keep her in the circular path?
  3. What minimum coefficient of static friction is required? Is the answer you found reasonable? In other words, is she likely to stay on the merry-go-round?

I just need help with #3

The minimum coefficient of static friction static friction required is μs =_______.

The answer is ______: (choose reasonable or unreasonable)

Because the value obtained is _______: (choose large and unrealistic / normal and realistic)

So she will ______: (choose be able to / not be able to) stay on the ride.
