As Scarlet and the parachute slow down, the drag decreases until it equals Scarlet's weight. At that point, what is her acceleration? Will the new ler minal speed be greater than, less than, or the same as the terminal speed before the parachute was opened?​

Consider a double atwood machine constructed as follows: a mass 4m is suspended from a string that passes over a massless pulley on frictionless bearings. the other end of this string supports a second similar pulley, over which passes a second string supporting a mass of 3m at one end and m at the other. using two suitable generalized coordinates, set up the lagrangian and use the lagrange equations to find the acceleration of the mass 4m when the system is released. explain why the top pulley rotates even though it carries equal weights on each side.
