1) water shoots out of a fire hydrant having nozzle diameter D with nozzle speed V0. what is the reaction force on the hydrant?
2) An inverted garbage can of weight W is suspended in air by water from a geyser. the water shoots up from the ground with a speed v0 , at a constant rate dm/dt. the problem is to find the maximum height at which the garbage can rides. what assumption must be fulfiled for the maximum height to be reached?
about the second question, i think that the assumption is that W equlas the force exerted from the water, but i don't know how to calculate the height.
thanks in advance.
