1. The problem statement, all variables and given/known data 1. Boat is towing two water skiers, each skier has it's own rope that's at 40 degrees the boats axis and the tension is 450N, how much force does the boat have to have to keep them all moving? 2. The plane is traveling at 200 km/h at the bottom of the loop, and the scale (the pilot happens to be sitting on one) reads 4x normal weight/Fg. What is the radius of the loop. 2. Relevant equations 1. I don't really know... 2. I don't really know... 3. The attempt at a solution My teacher put these on an assignment that's due tomorrow, so I really need some info fast. I'm thinking she missed out on some variable... Please correct me if I'm wrong.
