Directions: For a spinning amusement park ride, the velocity v in meters per second of a car moving around a curve with a radius r meters is given by the formula v= √ar, where a is the car’s acceleration in m/s2. 1. For safety reasons, a ride has a minimum acceleration of 39.2 m/s2. If the cars on the ride have a velocity of 14 m/s what is the smallest radius that any curve on the ride may have?

2. What is the acceleration of a car moving at 8m/s around a curve with a radius of 2.5m?
