A ship fires a projectile at a speed of 0.5c. What is the maximum speed another ship can have relative to the first and still be able to calculate the speed of the projectile using a Galilean transformation with no more than 1% error from the correct value for the velocity of the projectile

How do you tell if someone actually cares about you? and just say they do?

The ratio of lift to drag l/d for a wing or airfoil is an important aerodynamic parameter, indeed, it is a direct measure of the aerodynamic efficiency of the wing. if a wing is pitched through a range of angle of attack, l/d first increases, then goes through a maximum, and then decreases. consider an infinite wing with an naca 2412 airfoil. estimate the maximum value of l/d. assume that the reynolds number is 9x10^6.
