Hi. I have a HW question that asks me to find the "radial force" rerquired for someone to stay on a spinning merry-go-round. What is the radial force? thanx.

Radial just means along the direction of a radius of the circle--toward the center. (Radial as opposed to tangential.) FYI, "centripetal" means "toward the center" also.

Thank you; F_r = m omega^2 r.

Is it possible to use TeX mathematical expressions on this forum?
