Answer:
146.7 m
Explanation:
Given mass of the car, m = 1500 kg
speed of the car, v = 18 m/s
Centripetal force on the car, F = 3313.6 N
As car moves in circular motion, so the centripetal force on the car is given by
[tex]F_{centripetal} =\frac{mv^{2} }{r}[/tex]
Here, r is the radius of circle.
Substituting the given values in above formula, we get
[tex]3313.6=\frac{1500*(18^{2}) }{r}[/tex]
[tex]r=146.668 m[/tex]
r = 146.7 m
Thus, the radius of the circle is 146.7 m.
