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 the car is

Step-by-step solution

The angle of banking = v^2 r g Given, =45^ , r=90 ~m and g=10 ~m / s ^2 aligned 45^ & = v^2 90 10 v & = 90 10 45^ aligned Speed of car v=30 ~m / s
