Bill’s motorcycle can accelerate at 7.05m/s2 at a certain RPM and gear. How far, starting from rest, will Bill travel in the first 2.50s? How far to the nearest tenth does Bill travel?

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.
