You are in charge of keeping the drinks cold for a picnic. you have a styrofoam box that is filled with cola, water and you plan to put some 0 c ice in it. your task it to buy enough ice to put in the box at 6am so that the temperature stays at 0 c until the picnic starts at 6pm. you don't want to buy too mych ice because that means that you'll have less money to spend on food and other picnic items. you plan on keeping cold six 6-liter bottles of cola. how much ice will you need? today will be beautifully sunny: a perfect day for a picnic. the temperature will start out at 10 c at 6am and then the temperature will steadily incfrease, reaching 35 c at 6pm. it will be partially cloudy with a mild breeze from the west. assume: 1. coolers dimensions are .4m x .4m x .4m2. thickness of coller is 2cm3. temperature of cola when put in cooler is 20 c4. treat cola as water (specific heat and density)

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.
