Question $4$

The concrete block $(1\mathrm{.}5mx1\mathrm{.}4mx0\mathrm{.}8m)$ must slide up the $25$ ramp, without tipping. The density of concrete is $2500k\frac{g}{m^3}.$ The cable pulling the block at $A$ is parallel to the ramp and the coefficient of friction between the block and the ramp is $0\mathrm{.}15.$ Assuming a frictionless pulley, determine the possible range for the force $P$ in $kN.$
