1. The problem statement, all variables and given/known data http://i.imgur.com/hiNHMZZ.jpg - I am struggling with the right-hand page, questions b i, b ii and b iii. I am not sure how to calculate the total amount of kinetic energy transferred to the fluid when given the mass before and after the experiment? 2. Relevant equations EK = 1/2 x m x v^2 3. The attempt at a solution I was thinking maybe you use 7.5 ms^1 and work out the amount of KE before and after the experiment, then find the difference. I am doubting this because the fluid left the bottle at 7.5 ms^1 and I'm not sure if this is relevant to the final velocity of the fluid.
