The coefficient of static friction between him and the wall is μs. It’s all very funny until Sophia gets a hold of the controls and slows its rotational speed down until Ethan is just about to fall out. A) Let’s find the maximum period of rotation T of the funnel that will barely keep Ethan from falling out. Step 1: Draw all the forces on Ethan in the sketch above. Then add the forces together graphically in this box, identifying θ. Step 2: (Apply in two different directions…) Combine your two equations to eliminate FN
