(Problem 9.15) If you are rounding a corner on a bicycle, by twisting the handlebars of your bicycle to the right, which direction does the bicycle wheel precess? Why? Should you lean inward (to the right) or outward (to the left) to counteract this?

towards right,

lean inward to avoid tripping

Explanation:

The frictional force becomes centripetal force while turinig and presses on the wheel to maintain the grip of wheel on the road. Otherwise the bicycle will slip. So the press on the wheel is inward or towards the right when turning a corner to right

The rider has to lean inward ( to the right) to avoid tripping. Leaning inward, changes the direction of normal force on the wheels from vertical to slant. This helps to counter the torque produced by the frictional force

c the car's velocity increases constantly over time.
