A 50.0 kg child stands at the rim of a merry-go-round of radius 2.40 m, rotating with an angular speed of 3.05 rad/s.
(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?
Yes or No ?
Homework Answers
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
