1. ### Circular motion: could this happen?

wait im sorry, but i still get a wrong answer. the normal force is equal to the gravitational force. the force of static friction is equal to the force of drag. I can only find the normal force, which is just (9.8N/kg)M (mass is not given). what forces are responsible for the inward...
