Circular Motion A 650-kg car moving at 8.5 m/s takes a turn around a circle with a radius of 48.0 m. Determine the acceleration acting upon the car. Use a = v2/ r

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.

and filling in

and we need 2 significant digits in our answer. That means that

a = 1.5 m/sec²

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.
