A body is made up of multiple parts that are attached to each other by several compressed springs. It has been shot from a cannon and at the peak of its trajectory the springs are released, causing the parts to fly apart. The center of mass of the two parts
a. travels in a straight line at constant speed.
b. is now a meaningless concept.
c. follows a path which depends on the relative masses of the parts.
d. continues along the same parabolic path as before.

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
