50 points please help!! A car going 110 km/hr southwest reaches a curve in the road. Assume that the curve is an arc of a circle. After rounding the curve, the car's velocity is 110 km/h west. The car takes 2.50 s to round the curve.
a. what's the car's acceleration?
b. what is the length of the car's path on the road?
c. If the car instead maintained a steady speed of 100 km/h how long would it take to round the curve?
