What is the mass of a box if when I slide it across the ground it takes 10. N of applied force to move it at a constant velocity, and 50. N of applied force to accelerate it at 2.0 m/s^2?

What are the applications of electromagnetic waves

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.
