A 50 KG child is enjoying a coaster ride. the roller coaster car travels around the top of the circular loop with a radius of 29 m and a tangential velocity of 20 M/S at the very top of the loop what is the force due to gravity acting on the child? what centripetal force does the child experience? what is the magnitude of the supporting force that the child experiences?

Question

$$Force of Centripetal = mass*\frac{ velocity^{2} }{ radius }$$

Magnitude  of force supporting the child = force of centripetal + mg; 

I believe mg would be a negative value.
