1. The problem statement, all variables and given/known data You are watering your lawn with a hose when you put your finger over the hose opening to increase the distance the water reaches. If you are pointing the hose at the same angle, and the distance the water reaches increases by a factor of 4, what fraction of the hose opening did you block? 2. Relevant equations 3. The attempt at a solution This seems very obvious to me. The density of the water would remain consistent, thus the equation would become A1v1=A2v2. Since t is consistent as long as the height the water is fired from is, I figured this means v2 must be 4 times v1. But the answer is 2 times? I've looked over this problem many times and I just can't see what I'm missing, it seems so obvious?
