Springs: A very light ideal spring of spring constant (force constant) 2.5 N/cm is 15 cm long when nothing is attached to it. It is now used to pull horizontally on a 12.5-kg box on a perfectly smooth horizontal floor. You observe that the box starts from rest and moves 96 cm during the first 1.6 s of its motion with constant acceleration. How long is the spring during this motion?

Fill in the blank(s) with the appropriate word(s).

A circus performer stretches a tightrope between two towers. He strikes one end of the rope and sends a wave along it toward the other tower. He notes that it takes 0.8 s for the wave to travel the 20 m to the opposite tower. If one meter of the rope has a mass of 0.35 kg, find the tension in the tightrope

Determine the overall thermal resistance per unit area for the wall shown in Figure 2-51. Exclude the thermal resistance due to convection heat transfer in the analysis. Then, if the heat transfer is expected to be 190W/m^2 and the exposed brick surface is 10ÂșC, estimate the temperature distribution through the wall.
