Calculate the planetary phase angle (counterclockwise from earth, a = 1.0 au) that a probe may correctly complete a hohmann transfer orbit to venus (a = 0.7 au)

Water flows through a garden hose which is attached to a nozzle. the water flows through hose with a speed of 2.19 m/s and through the nozzle with a speed of 19.8 m/s. calculate the maximum height (in m) to which water could be squirted if it emerges from the nozzle and emerges with the nozzle removed.
