Question

what is the best way to minimize the effect of centrifugal force in a turn?
stop suddenly before entering the turn
speed up when approaching the turn.
make the turn as sharply as possible.
make the turn slowly.

Explanation:

Centrifugal force \(F = \frac{mv^{2}}{r}\) (where \(m\) is mass, \(v\) is velocity, \(r\) is radius of the turn). Slowing down (\(v\) decreases) reduces \(F\). Stopping suddenly is dangerous and not related to minimizing centrifugal force in - turn dynamics. Speeding up (\(v\) increases) makes \(F\) larger. A sharper turn (\(r\) decreases) makes \(F\) larger.

Answer:

Make the turn slowly.
