Answer:

[tex] 3470[/tex] N

Explanation:

[tex]m[/tex] = mass of the roller coaster = 150 kg

[tex]r[/tex] = Radius of the dip = 30 m

[tex]v[/tex] = Speed of the carriage = 20 m/s

[tex]N[/tex] = Normal reaction

Force equation for the motion is given as

[tex]N - mg = \frac{mv^{2}}{r}[/tex]

[tex]N - (150) (9.8) = \frac{(150)(20)^{2}}{30}[/tex]

[tex]N = 3470[/tex] N
