Find the minimum force required to keep a block of mass m in equilibrium on a rough inclined plane with inclination α and coefficient of friction μ(<tanα).

the time of flight is found to be t. The acceleration with which the lift is moving up is When a body is thrown up in a lift with a velocity u relative to the lift
