The hose is held at an angle 0 = 30° with the horizontal, and the water is discharged at A with a speed of vд = 40 ft/s. If the water stream strikes the building at B, determine the two possible distances s from the building. Part2 Water is discharged from the hose with a speed of 40 ft/s. Determine the two possible angles the firefighter can hold the hose so that the water strikes the building at B. Take s = 20 ft.
