A volcano shoots old blobs of molten lava called lava bombes from its summit. A geologist observing the irruption uses a stopwatch to time the flight of a particular lava bomb that is projected straight upwards. If the time for the bomb to rise and fall back to its launch height is 4.75 s, and it's acceleration is 9.8 m/s^2 downward, what is its initial speed?
