A snow blower travels forward at a constant speed v_s = 1.4 ft/sec along the straight and level path shown. The snow is ejected with a speed v_r = 30 ft/sec relative to the machine at the 40° angle indicated. Determine the distance d which locates the snow blower position from which an ejected snow particle ultimately strikes the slender pole P. At what height h above the ground does the snow strike the pole? Points O and Q are at ground level.
