Problem

An inclined plane is bent in such a way that the vertical cross-section is given by

y = \frac{x^2}{4}

where

y

is in vertical and

x

in horizontal direction. If the upper surface of this curved plane is rough with coefficient of friction

\mu = 0.5

, the maximum height in cm at which a stationary block will not slip downward is _____ cm.
