Question

A ramp is constructed in parabolic shape such that the
height y of any point on its surface is given in terms of the
point's horizontal distance x from the bottom of the ramp be
y = x²/2L. A block of granite is to be set on the ramp; the
coefficient of static friction is 0.80. What is the maximum x
coordinate at which the block can be placed on the ramp
and remain at rest, if L = 10 m?
