Araised flower bed requires 13 cubic feet of garden soil. you can get a good deal by importing the soil, but it is sold from the dealer in cubic meters. to the nearest hundredth, how many cubic meters of soil is needed? there are 3.28 feet in 1 meter.

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.
