Mohair, animal-hair fibre obtained from the Angora goat and a significant so-called specialty hair fibre. The word mohair is derived from the Arabic mukhayyar (âgoatâs hair fabricâ), which became mockaire in medieval times. Mohair is one of the oldest textile fibres, produced exclusively in Turkey for thousands of years and achieving importance in European textile manufacture during the 19th century.

We know that gravity will always act vertically downward on the projectile. The air resistance creates a force, that is always in the opposite direction to the velocity. From Newton's second law, $F = m a$, we can see that this force will have its effect by changing the acceleration of the cannon ball.hen the projectile is fired from a height $h_0$ above the landing ground the angle for maximum range is not 45 Â° but it can be found in a similar way. Take the equation for range from a height, and differentiate.
