A box of mass 3.0 kg slides down a rough vertical wall. The gravitational force on the box is 29.4 N. When the box reaches a speed of 2.5 m/s, you start pushing on one edge of the box at a 45° angle (use degrees in your calculations throughout this problem) with a constant force of magnitude F, = 23.0 N, as shown in (Eigure 1). There is now a frictional force between the box and the wall of magnitude 13.0 N. How fast is the box sliding 3.0 s after you started pushing on it? I Review | Constants Still using our simplified model (in which we do not know the magnitudes of the forces), draw a free-body diagram showing all the forces acting on the box after you start pushing on it. The positive y axis is taken to be upward. The black dot represents the box. Since our model is about having constant forces of unknown magnitude, you do not need to draw the vectors to scale, but your final diagram should be physically reasonable. Draw the vectors starting at the black dot. The location and orientation of the vectors will be graded. The relative lengths of the vectors will not be graded.

- Figure above shows the cross section of a wall made of two layers. The thickness of the 2 nd layer is L2= 0.70L1. The thermal conductivities of the layers are 0.25 and 0.75 W/mK, respectively and thermal conduction is steady. If the temperatures at inlet and between the layers are Ti = 30.0°C and T=8 °C, respectively; what is the outside temperature To for unit area?
