please help with all answers:

A $50\mathrm{.}0$ kg child stands at the rim of a merry$-$go$-$round of radius $2\mathrm{.}10$ m $,$ rotating with an angular speed of $3\mathrm{.}00$ rad$/$s$.$

$($a$)$ What is the child's centripetal acceleration?

m$//$s$^(2)$

$($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?

$($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?
