Answer:

Explanation:

The mass of the car doesn't matter because On a flat curve the mass of the car does not affect the speed at which it can stay on the curve. You would need the mass if you were solving the the centripetal force acting on the car, but not the acceleration.

[tex]a=\frac{v^2}{r}[/tex] and filling in

[tex]a=\frac{(8.5)^2}{48.0}[/tex] and we need 2 significant digits in our answer. That means that

a = 1.5 m/sec²
