Athree-wheeled car moving along a straight section of road starts from rest, accelerating at 2.00 m/s2 until it reaches a speed of 35.0 m/s. then the vehicle moves for 83.0 s at constant speed until the brakes are applied, stopping the vehicle in a uniform manner in an additional 5.00 s. (a) how long is the three-wheeled car in motion (in s)? 105.5 s (b) what is the average velocity of the three-wheeled car for the motion described? (enter the magnitude in m/s.) m/s

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.
