A homogenous block of mass m, width b and height h is resting on a rough horizontal surface A horizontal force F is applied to it , which makes it to move with a constant velocity . The coefficient of friction between block and surface is mu Find the greatest height at which force F may be applied to slide the block with out tipping over

A block is kept on a rough horizontal surface. A variable horizontal force is acting on the block as shown in the figure. At t=0 , block is at rest. Kinectic energy of block at t=5 sec will be (g=10m//s^(2))
