A jet of water issues out from a fire hydrant nozzle fitted at a height of 3 m from the ground at an angle of 45 degrees with the horizontal. If the jet  under a particular flow condition strikes the ground at a horizontal distance of—assume values with decimals between 15 to 20 m— m from the nozzle,  find the jet velocity and the maximum height the jet can reach and its maximum horizontal distance from the nozzle. Neglect air resistance
