 Homework Statement:
 A force F is applied to a box of weight P (rigid body). If u is the coefficient of friction, determine the minimum value for h that allows the body to slide without overturning backwards.
 Relevant Equations:

L = r x p = r x mv
dL/dt = r x F
My attempt:
When the body is about to overturn backwards, the normal force and frictional force are applied on point A.
If I want to avoid overturning, torque must be 0. Then, I calculate torque with respect to A.
The value I get for h is negative, implying there is no minimum value for h.
What am I doing wrong?
