In what direction does a plane accelerate when it is performing a banking turn?

What point should the hammer be released?

The hammer should be released when the rope attached to the hammerhead is perpendicular to the direction which the hammerhead must go. This is due to the fact that the linear velocity of the hammerhead is perpendicular to the centripetal force acting on the object. To maximize distance, releasing it at the point where its linear velocity is at its maximum point out of the cage is ideal.

The hammer should be released when its tangential force is in the direction of which the athlete intends the hammer to move

What is providing the centripetal force on a car?

The car is moving in a circle, therefore there is a constant change in velocity (velocity is a vector) even if the speed is constant. A change in velocity means there is an acceleration so there must be a force acting on the car.

The centripetal force acting on the plane is always perpendicular to the velocity (The direction in which the plane is travelling). It accelerates in the direction that is perpendicular to the direction of centripetal force that acts above the plane.

In what direction does a plane accelerate when it is performing a banking turn?

Due to the wings (the part called the airfoil), the pressure distribution is not the same throughout. The pressure on the top is slightly less than that on the bottom so a net upwards force is created. This is called lift. When an airplane is turning, the lift will point towards the center of the 'circle' (or what would be a circle if traced out fully)
and provides the centripetal force.

As the car turns, the centripetal force is directed towards the centre of the circle. By raising the racetracks, there is a reaction force in the direction of the turn.

As you are not connected to the car, as the car turns, you as the passenger continue to move in the previous direction, where until you are pushing against the walls of the car, you are not moving in the same direction as the car.

Ms. Trunchbull really hates little girls with pigtails. At what point does she have to release her to throw Amanda Thripp out the window?
