A200n force pushes forward on the 20kg truck. the truck pulls two crates connected together by ropes, as shown. the gravitational constant is 10n/kg. determine the acceleration of the crates and truck and the tension in each rope for one of the following sets of conditions. me! i am really confused on how to draw the diagrams and how to find the x component forms and the unknowns! i've tried working on it but ended up erasing it cause it seemed wrong.

Acarpenter builds an exterior house wall with a layer of wood 2.9 cm thick on the outside and a layer of styrofoam insulation 2.3 cm thick on the inside wall surface. the wood has k=0.080w/(m⋅k), and the styrofoam has k= 0.010 w/(m⋅k). the interior surface temperature is 19.0 ∘c , and the exterior surface temperature is -15.0 ∘c . a.)what is the temperature at the plane where the wood meets the styrofoam? celsius b.)what is the rate of heat flow per square meter through this wall? /m^2
