Question

Maximum speed: The maximum speed (v) that an automobile can travel around a curve of radius r without skidding is given by the equation v=√5r/2 where v is in miles per hour and r is measured in feet. What is the maximum speed a car can travel around a curve with a radius of 250 feet without skidding?

Answer 1

Just plug r = 250 into the equation then simplify the radical.
