Runner A is initially 3.87 mi West of a flag pole in is running with a constant velocity of 5.86mi/h due east. Runner B is initially 2.90 mi east of the flagpole and is running with a consent velocity of 5.06 mi/h due west. How far are the Vernice from flagpole when they meet? (West is positive and east is negative) Please Help!!!

Determine the amount of work done when a crane lifts a 100-n block form 2m above the ground to 6m above the ground

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.
