Substitute that infromation in to the equation (wonder if this equation is true )Originally Posted by mathAna1ys!5
However, must be converted to feet per second,
Thus, (use arctan)
highway curves.... proper banking angle, theta, for a car making a turn of radius, r feet at a velocity v feet per second is given by tan theta = v^2 /gr, where g is the acceleration due to gravity. assume g = 32 ft/s^2. an engineer is designing a curve with a radius of 1000 feet. if the speed limit on the curve will be 55mph, at what angle should the curve be banked?
