A model rocket is propelled upward by a cylinder of compressed water. The cylinder emits water at a rate of 0.050 kg/second with an exit speed of 80.0 m/s. Initially, the rocket has a mass of 0.15 kg, including the water cylinder. What is the rocket's initial upward acceleration? Don't forget to add in the downward force of gravity.
