The force of air impact upon the sail of a boat is greater if the air

Question

Quizplus · Accepted Answer

The force of air impact upon the sail of a boat is greater if the air encounters the sail head-on. This is because when the air hits the sail head-on, it pushes it directly, creating a larger force. When the air encounters the sail at a grazing angle, it will still create some force but it will not be as much as when it is hitting the sail head-on. The option A is not possible as air cannot bounce upon impact as it is a fluid and does not have a solid surface.
