Recall the centripetal force formula.
[tex]F_c=\frac{mv^2}{r}[/tex]
Next, substitute the given terms.
[tex]F_c=\frac{(800)(14)^2}{52}[/tex]
[tex]F_c=\frac{(800)(196)}{52}[/tex]
[tex]F_c=\frac{156,800}{52}[/tex]
[tex]F_c=3015.38461538[/tex] [tex]N[/tex]
To conclude, an 800 kg car which rounds a rotunda on a smooth, level road of radius 52 and is at a speed of 14 m/s has a centripetal force of 3,015.38 N.
