Surely they mean centrifugal force? That’s what sticks you to the banking.
CENTRIPETAL
You hit the corner (or the olympic hammer tries to fly in a straight line away fro the thrower) and the banking pushes you in (the rope pulls it in a circle), that’s the centripetal force acting to the center.
Centrifugal force is the inertial force (also known as imaginary force), it’s what balances the equation, it’s like trying to push a car (brakes off) down the road, you push on it, it doesn’t push back but you do feel it pushing back because the car’s inertia is balancing your pushing. If the car’s brakes are on, or the road was uphill then it would be pushing back.
Maybe it’s leading into a ‘compare and contrast’ type question?
F1 cars on a flat track sacrifice drag for downforce, track riders have too little power to want to sacrifice any, and are held in place by the banking and centripetal force.
