Question:

At a playground, a 22-kg child sits on a spinning merry-go-round, as shown from above in FIGURE 6-71. The merry-go-round completes one revolution every 6.2 s, and the child sits at a radius of r = 1.4 m.

(a) What is the force of static friction acting on the child?

(b) What is the minimum coefficient of static friction between the child and the merry-go-round to keep the child from slipping?
