372181 A cannon of mass \(1000 \mathrm{~kg}\), located at the base of an inclined plane fires a shell of mass \(100 \mathrm{~kg}\) in a horizontal direction with a velocity \(180 \mathrm{~km} / \mathrm{h}\). The angle of inclination of the inclined plane with the horizontal is \(45^{\circ}\). The coefficient of friction between the cannon and the inclined plane is 0.5 .
