The homogeneous rectangular block of mass m, width b, and height H is placed on a horizontal surface and subjected to a horizontal force P, as shown in the following figure. The coefficient of friction between the block and the surface is u. (a) Determine the largest value of h so that the block will slide without tipping over. (b) Determine the location of a point C on the bottom face of the block through which the resultant of H the friction and normal forces acts if h=
