A 50.0 kg child stands at the rim of a merry-go-round of radius 1.65 m, rotating with an angular speed of 2.75 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?
Physics question please give answer and explanation?
a.
a(c)= r(omega)²
=1.65(2.75²)
=12.48 m/s²
b.
F(c) = mv²/r
=50(12.48)
=623.9 N
