Kool-Aid contains Allura Red dye. A student makes a Kool-Aid solution by diluting 61.2 mg of Kool-Aid with water to a total volume of 25.00 mL using a volumetric flask. Because this solution is too concentrated (measured absorbance > 1.0), the student then dilutes a small sample of the Kool-Aid solution by taking 0.500 mL of the solution and mixing it with 0.500 mL of water (a ½ dilution). The absorbance of the ½ diluted solution is 0.315. Using the Beer’s Law curve, determine the concentration of the dye in the original Kool-Aid.

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.
