A graduate student wants to use van der Waals' equation to express the pressure-volume- temperature relations for a gas. Her project requires a reasonable degree of precision in the p-V-T calculations. Therefore, she made the following experimental measurements with her setup to get an idea of how easy the experiment would be: Temperature, K Pressure, atm Volume, ft'/lb mol 273.1 273.1 200 1.860 1000 0.741 Determine values of constants a and b to be used in van der Waals' equation that best fit the experimental data.

A mass of 1.25 kg stretches a spring 0.06 m. The mass is in a medium that exerts a viscous resistance of 66 N when the mass m has a velocity of 6 . The viscous resistance is proportional to the - S speed of the object. Suppose the object is displaced an additional 0.03 m and released. Find an function to express the object's displacement from the spring's natural position, in m after t seconds. Let positive m as the s2 displacements indicate a stretched spring, and use 9.8 acceleration due to gravity. u(t) = %3D
