Both blocks have equal mass and there is no friction between A and the horizontal surface. A horizontal time dependent force F=kt is applied on the block A. At what time will block B topple? Assume that friction between the two blocks is large enough to prevent B from slipping.

Figure shows a vertical force applied tangentially to a uniform cylinder of weight Fg. The coefficient static friction between the cylinder and both surface is 0.500. In terms of Fg find the maximum force P that can be applied that does not cause the cylinder to rotate. Rectangular block B
