Answer:
The radius = 170.21 m
Explanation:
The given data are : -
The centripetal acceleration of a car = 9.40 m/s².
Speed of a car = 40.0 m/s .
We have to calculate the radius ( r ) of of curve.
The centripetal acceleration ( a ) is given by
a = [tex]\frac{v^{2} }{r}[/tex]
r = [tex]\frac{v^{2} }{a}[/tex] = [tex]\frac{40^{2} }{9.40}[/tex] = [tex]\frac{1600}{9.40}[/tex] = 170.21 m
