<PRE><B>Question 686539</B>
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.
ca = k/r
-----------------

If the passengers feel an acceleration of 4 feet per second per second when the radius of the turn is 100 feet, 
----
4 = k/100
k = 400
-----
Equation:
find the acceleration the passengers feel when the radius of the turn is 200 feet.
----
ca = 400/200
ca = 2 ft/sec
