A car of mass 1000 kg negotiates a banked curve of radius 90 m on a frictionless road . If the banking angle is 45^@ , the speed of car is :

A car of mass 1000 kg is negotiating an unbanked curve of radius 20 m. If the coefficient of friction is 0.5 and g = 10 m//s^(2) the maximum safe speed of the car is

A car is moving along a banked road laid out as a circle of radius r . (a) What should be the banking angle theta so that the car travelling at speed v needs no frictional force from tyres to negotiate the turn ? (b) The coefficient of friction between tyres and road are mu_(s) = 0.9 and mu_(k) = 0.8 . At what maximum speed can a car enter the curve without sliding toward the top edge of the banked turn ?
