(a) What is the child's centripetal acceleration?
______ m/s2

(b) What is the minimum force between her feet and the floor of the carousel that is required to keep her in the circular path?
______ N

(c) 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?

Answer #1

@ Centripetal asalectic Q = ☆ = way ac = (3.05) ?x 2-40 = 22-326 mysz 6 minimum funce, Fe = mae = 50 x 22:326 = 1116.3 N © Co

d.
No, the answer is not reasonable . It is too high a value to be true. She will no stay on the merry go around
