SP1b. During a 5.0 second interval, an object's velocity changes from 25 meters per second
east to 15 meters per second east. Determine the magnitude and direction of the
object's acceleration.

In a system, when potential energy decreases, then entropy also decreases. true false

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.
