Question 888632: While traveling at a constant speed in a car, the centrifugal acceleration passengers feel while the car is turning is inversely proportional to the radius of the turn. If the passengers feel an acceleration of 10 feet per second when the radius is 70 feet, find the acceleration the passengers feel when the radius of the turn is 140 feet.
A. 8feet per second per second
B. 6feet per second per second
C. 7feet per sec per sec
D. 5feet per sec per sec

As the question says, the centrifugal acceleration is inversely proportional to the radius. That means that if the radius doubles, the acceleration, inversely, will be halved.
Since 140 = 70x2, the radius is doubled. The acceleration is thus halved, from 10 to 5.
Answer: D
