Solve the problem.A formula used by an engineer to determine the safe radius of a curve, R, when designing a particular road is: 
where ? is the superelevation of the road and V is the velocity (in feet per second) for which the curve is designed. If 
f = 0.1
, and 
find V. Round to the nearest foot per second.
A. V = 74 ft per sec B. V = 71 ft per sec C. V = 69 ft per sec D. V = 67 ft per sec
