A small car travels at constant speed on the inside of a track that is a vertical circle with radius 5.00 m. ?

If the normal force exerted by the track on the car when it is at the top of the track (point B) is 6.00 N, what is the mass of the car? 


the constant speed of the car is 12 m/s, forgot to mention that

    m*V^2/r-m*g = 6 

    m(V^2/5-g) = 6

    m = 6/(V^2/5-g) 

    ...where the quantity V^2/5-g must be positive (V^2/5 > g)

      just to clarify, is the -g inside or outside the fraction?
