Thanks for the quick reply. By using the formula P = mv, I am able to find the momentum of the water leaving rocket. 0.04 kg * 4.05 m/s [E] = 0.162 kg*m/s [E] I am assuming that momentum is similar to force and would give the the rocket a momentum of 0.162 kg*m/s [W]. I could then find the...

Homework Statement A 15.0 g plastic water rocket containing 40.0 g of water and compressed air is strung on a very low friction horizontal wire. When fired, compressed air forces the water from the rocket in 0.600 s at an average exit velocity of 4.05 m/s [E]. Based on the information in the...
