Three blocks are placed in contact on a horizontal frictionless surface. a constant force of magnitude f is applied to the box of mass m. there is friction between the surfaces of blocks 2m and 3m (μs = 0.26, μk = 0.15) so the three blocks accelerated together to the right.
what is the acceleration of the blocks? (you may assume block 3m does not slide or fall off block 2m.)
what is the maximum force f that can be applied, before the 3m block slides off?

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.
