A block of mass is placed on a surface with a vertical cross section given by `y=x^3/6`. If the coefficient of friction is 0.5, the maximum height above the ground at which the block can be placed without slipping is:

A block of mass m is placed on a surface with a vertical cross section given by y =(x^(3))/(6) If the coefficient of friction is 0.5, the maximum height above the ground at which the block can be placed without slipping is :

A block of mass 'm' is placed on a rough surface with a vertical cross section of y =(x^(3))/(6) . If the coefficient of friction is 0.5 , the maximum height above the ground at which the block can be placed without slipping is .

A block is placed on a ramp of parabolic shape given by the equation y=x^(2)//20 . If mu_(s) = 0.5 , then the maximum height above the ground at which the block can be placed without slipping is
