A car starts from rest at a stop sign. It accelerates at 2.0 m/s2 for 6.7 seconds, coasts for 2.8 s , and then slows down at a rate of 1.5m/s2 for the next stop sign. PART A : How far apart are the stop signs? (Please explain how you got the answer too, thanks:))

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.
