(a) Find the maximum speed at which a vehicle can turn round a curve of 20m radius on a level road, mu_(s)=0.5 . (b) A circular track of radius 100 m is to be designed for vehicles at an average speed of 72km//h . Find the angle of banking of the track.
A train rounds an unbanked circular bend of radius 30 m at a speed of 54 km//h The mass of the train is 10^(6) kg What provides the centripetal force required for this purpose ? The engine or the rails ? What is the angle of banking required to prevent out the rails ?
The angle of elevation from a point on the bank angle of the top of temple on the other bank is 45^(@) Retreating 50m the observer finds the new angle of elevation is 30^(@). What is the width of the river
A turn of radius 600 m is banked for a vehicle of mass 200 kg going with a speed of 180kmh^(-1) . Determine the banking angle of its path.
A man standing on the bank of a river observes that the angle of elevation of the top of a tree just on the opposite bank is 60^(@) . The angle of elevation is 30^(@) from a point at a distance y m from the bank of the river. What is the height of the tree ?
