In exploration #2 of this activity you investigated what the motion of a simulator model in the final stages of this experiment, rather than the real cart and track? cart would be like with no friction. why do you think you used the examples of contact push/pull interactions. while watching a moving object, what evidence would you look for to tell you that it is currently involved in a contact push/pull interaction of any type? s4. in the first few activities of this unit you have seen some different s5. suppose it were possible for you to start an object moving by giving it a quick push, and then arrange for it to be free of the influence of any interactions whatsoever. after the initial push, do you think it would speed up, slow down, or keep moving at a constant speed? explain your reasoning using ideas about energy transfers and changes. s6. two students were discussing their ideas about how the speeds of objects change when they are involved in a contact push/pull interaction

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
