5. A circular curve of highway is designed for traffic moving at a speed V. If the radius of the curve is r, what is the correct angle of banking of the road such that no friction force would be needed to negotiate it? 6. With the coefficient of static friction between the floor of a truck and a box resting on given, if the truck has an initial velocity of Vi , what is the least distance in which the truck can stop if the box is never to slide?
