. Indiana Jones needs to ascend a high-rise building. There is a large hose filled with pressurized water hanging down from the building top. He builds a square platform and mounts four 4-cm-diamter nozzles pointing down at each corner. By connecting hose branches, a water jet can be produced from each nozzle. Jones, the platform, and the nozzles have a combined mass of 150 kg. Determine the minimum water jet velocity needed to raise the system.
