I have this question I have to answer about Centripetal Force...? I don't know how to do it.
A child, who has a mass of 47900g, is sitting 6.20m from the center of a playground merry-go-round that is spinning at 1.25 radians/sec. The height of the a merry-go-round is 2.75m. What is the centripetal force?
Can someone help me solve this problem?

The height makes no difference.
A standard formula for centripetal force is F = mw^2r (w is 'omega', angular velocity in rad/s)
You have to get the units right - mass in kg
F = 47.9 x 1.25^2 x 6.20 = 464N
(Another formula you use is F = mv^2 / r if you know the velocity v.)
