Solve the all parts of given question:
Question: A child stands at the rim of a rotating merry-go-round of radius 2.6 m. The child has a mass of 56.0kg, and the carousel turns with an angular velocity of 2.5 rad/s.
Part A: What is the child's centripetal acceleration?
Part B: What is the horizontal force required between her feet and the floor of the carousel to keep her in the circular path?
Part C: What minimum coefficient of static friction is required? (This will tell you whether she is likely to be able to stay on the merry-go-round).
I need help to find the horizontal force required between her feet and the floor of the carousel to keep her in the circular path.
